I agree w/ this...

I also agree w/ this...

This does not justify throwing the baby out w/ the bathwater.  GNUstep gui is
useable for making UI based solutions, it's just not fast and stable.   We need
to continue to use it and make fixes/optimizations where necessary.  This is
the only way it will gain the stability and speed it needs.

We can improve the quality of the gui code by continuing to test and optimize
it.  Helge seems bent on *replacing* gstep-gui w/ GTK which I, personally,
think is somewhat extreme.  Replacing gui w/ GTK is like saying "Well, we're
not satisfied with our first crack at it, so why don't we just throw it all
away and start again."

Please see comments above about "testing and optimizing".   The complexity of
the text system is something we will have to deal w/ no matter what the gui
library is based on.

I don't think that this is a problem w/ GNUstep so much as it is a problem w/
WindowMaker.

Very true.
