! Small but important fixes needed in existing features:
  
! * Make compile.el record the markers that point to error loci
!   on text properties in the error message lines.
! 
! * Fix the kill/yank treatment of invisible text. At the moment,
    invisible text is placed in the kill-ring, so that the contents of
    the ring may not correspond to the text as displayed to the user. It
    ought to be possible to omit text which is invisible (due to a
    text-property, overlay, or selective display) from the kill-ring.
  
! Important features:
  
! * Provide user-friendly ways to list all available font families,
    display a font as a sample, etc.  [fx is looking at multilingual
    font selection for Emacs 22.]
  
! * Program Enriched mode to read and save in RTF.  [Is there actually a
    decent single definition of RTF?  Maybe see info at
    http://latex2rtf.sourceforge.net/.]
  
! * Implement something better than the current Refill mode.  This
    probably needs some primitive support.
  
! * Implement primitive and higher-level functions to allow filling
    properly with variable-pitch faces.
  
! * Implement a smoother vertical scroll facility, one that allows
    C-v to scroll through a tall image.
  
! * Implement other text formatting properties.
! ** Footnotes that can appear either in place or at the end of the page.
! ** text property that says "don't break line in middle of this".
     Don't break the line between two characters that have the
     same value of this property.
! ** Discretionary hyphens that are not visible when they are at end of line.
  
! * Make movemail work with IMAP.
  
! * Internationalize Emacs's messages.  [Note that this is of limited
    use until the menus can display multilingual text.  It also doesn't
    address important issues like using the names of symbols essentially
    as documentation, e.g. in command names and Custom.  -- fx]
  
! * Make the Lucid menu widget display multilingual text.  [This
    probably needs to be done from actual Emacs buffers, either directly
    in the menu or by rendering in an unmapped window and copying the
    pixels.  Note that the relevant Xlib functions assume a specific

    port now displays multilingual text in menus, but only insofar as
    Emacs can encode it as utf-8 and gtk can display the result.]
  
! * Remove the limitation that window and frame widths and heights can
    be only full columns/lines.
  
! Other features we would like:
  
! * Have a command suggestion help system that recognizes patterns
    of commands which could be replaced with a simpler common command.
    It should not make more than one suggestion per 10 minutes.
  
! * Add a way to define input methods by computing them (when first used)
    from other input methods.  Then redefine C-x 8 to use a
    user-selected input method, with the default being the union of
    latin-1-prefix and latin-1-postfix.
  
! * Implement a clean way to use different major modes for
    different parts of a buffer.
  
! * Give start-process the ability to direct standard-error
    output to a different filter.
  
! * Make desktop.el save the "frame configuration" of Emacs (in some
    useful sense).
  
! * Give desktop.el a feature to switch between different named
    desktops.
  
! * Replace finder.el with something that generates an Info file
    which gives the same information through a menu structure.  [Dave
    Love started on this.]
  
! * Implement a variant of uncompress.el or jka-compr.el that works with
    GNU Privacy Guard for encryption.  [Code exists but isn't assigned.
    See the Gnus development sources for assigned code concerning GPG
    use with mail, which is probably a good start.]
  
! * Save undo information in files, and reload it when needed
    for undoing.
  
! * Merge the Emacs regex.c with the Glibc regex.c.
    They split off a few years ago through negligence.
  
! * Change the Windows NT menu code
    so that it handles the deep_p argument and avoids
    regenerating the whole menu bar menu tree except
    when the user tries to use the menubar.

! ** Remove the limitation that window and frame widths and heights can
    be only full columns/lines.
  
! * Other features we would like:
! 
! ** Ability to map a key, including all modified-combinations.
!    E.g map mouse-4 to wheel-up as well as M-mouse-4 -> M-wheel-up
!    M-C-mouse-4 -> M-C-wheel-up, H-S-C-M-s-double-mouse-4 ->
!    H-S-C-M-s-double-wheel-up, ...
! 
! ** Beefed-up syntax-tables.
! *** recognize multi-character syntactic entities like `begin' and `end'.
! *** nested string-delimiters (for Postscript's (foo(bar)baz) strings).
! *** support for infix operators (with precedence).
! *** support for the $ (paired delimiter) in parse-partial-sexp.
! *** support for hook-chars whose effect on the parsing-state is specified
!       by elisp code.  Thus a char could both close a string and open a comment
!       at the same time and do it in a context-sensitive way.
! *** ability to add mode-specific data to the partial-parse-state.

    of commands which could be replaced with a simpler common command.
    It should not make more than one suggestion per 10 minutes.

*** 111,194 ****
    thread has processed the MENU_BAR_ACTIVATE_EVENT and regenerated
    the whole menu bar.  In the mean time, it should process other messages.
  
! * Get some major packages installed: W3/url (development version needs
    significant work), PSGML.  Check the assignments file for other
    packages which might go in and have been missed.
  
! * Make keymaps a first-class Lisp object (this means a rewrite of
    keymap.c).  What should it do apart from being opaque ?
    multiple inheritance ?  faster where-is ?  no more fix_submap_inheritance ?
    what else ?
  
! * Provide real menus on ttys.  The MS-DOS implementation can serve as
    an example how to do part of this.
  
! * Implement popular parts of the rest of the CL functions as compiler
    macros in cl-macs.
  
! * Highlight rectangles (`mouse-track-rectangle-p' in XEmacs).  Already in CUA,
    but it's a valuable feature worth making more general.
  
! * Support simultaneous tty and X frames.
  
! * Provide MIME support for Rmail using the Gnus MIME library.  [Maybe
    not now feasible, given Gnus maintenance decisions.  fx looked at
    this and can say where some of the problems are.]
  
! * Eliminate the storm of warnings concerning char/unsigned char
    mismatches that we get with proprietary compilers on various systems.
    They make it difficult to spot the important warnings.
  
! * Fix anything necessary to use `long long' EMACS_INTs with GCC.
  
! * Split out parts of lisp.h and generate Makefile dependencies
    automatically.
  
! * Update the FAQ.
  
! * Allow auto-compression-mode to use zlib calls if zlib is available.
    [It's required for PNG, so may be linked anyhow.]
  
! * Add a --pristine startup flag which does -q --no-site-file plus
    ignoring X resources (Doze equivalents?) and most of the
    environment.  What should not be ignored needs consideration.
  
! * Investigate using the language environment (or locale?) to set up
    more things, such as the default Ispell dictionary, calendar
    holidays, quoting characters?,...
  
! * Improve the GC (generational, incremental).  (We may be able to use
    the Boehm collector.)  [See the Boehm-GC branch in CVS for work on
    this.]
  
! * Check what hooks would help Emacspeak -- see the defadvising in W3.
  
! * Add horizontal scroll bars.
  
! * Provide an optional feature which computes a scroll bar slider's
    size and its position from lines instead of characters.
  
! * Make the Custom themes support do useful things.
  
! * Investigate using GNU Lightning or similar system for incremental
!   compilation of selected bytecode functions to subrs.  Converting CCL
!   programs to native code is probably the first thing to try, though.
! 
! * Add support for SVG (Scalable Vector Graphics) rendering to
    Emacs.
  
! * Allow unknown image types to be rendered via an external program
    converting them to, say, PBM (in the same way as PostScript?).
  
! * Allow displaying an X window from an external program in a buffer,
    e.g. to render graphics from Java applets.  [gerd and/or wmperry
    thought this was feasible.]
  
! * Allow images (not just text) in the margin to be mouse-sensitive.
    (Requires recursing through display properties).  Provide some way
    to simulate mouse-clicks on marginal text without a mouse.
  
! * Implement Lisp functions to determine properly whether a character
    is displayable (particularly needed in XFree 4, sigh).  Use it to
    define useful glyphs that may be displayed as images or unicodes
    (with ASCIIfied fallback via latin1-disp).  Examples include

    tree displays generally, mode-line mail indicator.  [See work done
    already for Emacs 22 and consult fx.]
  
! * Do something to make rms happy with fx's dynamic loading, and use it
    to implement things like auto-loaded buffer parsers and database
    access in cases which need more than Lisp.
  
! * Extend ps-print to deal with multiple font sizes, images, and extra
    encodings.
  
! * Provide portable undumping using mmap (per gerd design).
! 
! * Replace gmalloc.c with the modified Doug Lea code from the current
!   GNU libc so that the special mmapping of buffers can be removed --
!   that apparently loses under Solaris, at least.  [fx has mostly done
!   this.]
  
! * Use the XIE X extension, if available, for image display.
  
! * Make monochrome images display using the foreground and background
    colors of the applicable faces.
  
! * Add support for rendering antialiased text, probably using
    XRender/Freetype.
  
! * Rewrite make-docfile to be clean and maintainable.
! 
! * Port the conservative stack marking code of Emacs' garbage collector
    to more systems, so that we can completely get rid of GCPROs.
  
! * Reorder defcustom's in each package so that the more important
    options come first in the Customize buffers.  This could be done by
    either rearranging the file (since options are shown in the order
    they appear in the *.el files), or by adding a few :set-after
    attributes.
  
! * Maybe document the features of libraries missing from the manual (or
    ancillary manuals, including the Lisp manual in some cases).
    This is not worth doing for all of these packages and we need not
    aim for completeness, but some may be worth documenting.
