I think that it would be safe that the GUI is stable enough to replace
a few parts of the GUI that the WidgetSet didn't covered (mostly the
RaceGUI), which probably will require the addition of a few features.
After that, sometime in early January, I hope to make user-visible
improvements to the GUI, I have already begun to investigate what to
do, and for those who don't know, created a section in the game design
ideas wiki page for input.
