That's the problem - basically all of it is already there in 
DLangUI, it's done, complete, working, and has been for a few 
years. But programmers being programmers, prefer ignoring 
existing libraries and keep reimplementing the same stuff from 
scratch. In most cases it doesn't go too far, as the steam dries 
out. In some cases it does go far, we get one more UI library 
that nobody uses, and instead other people reimplement the same 
from scratch and keep asking what's holding us back... It's a 
cultural thing, I guess. ;)
