well, nibs are difficult to port and we don't have an NSToolbar (but you
could write one and contribute it if you want ...) - about JIGS, well it's
sort of untested with the gui library - wrappings for most classes are
missing ... but they are very easy to add, you just add the classes and
methods to the .jigs file and JIGS does the rest.

the only real `stopping' problem I might see is if you are say subclassing
NSView to draw your own custom view in your own way ... because
inter-language subclassing (eg subclassing an ObjC class in Java) has
quite some problems - it has never been really finished/fixed - mostly
because it's not trivial and I've never really needed it.  it's the most
outstanding missing feature of JIGS - so if you are using it as a
fundamental part of your app, that might be a very serious problem.
