In closing, I will just end in saying that you have some difficult decisions to make ahead. Not just questions about GUI or the key bindings,but the more historically neglected things such as documentation or easy installation. KDE cannot be everything to everyone, and that will be a hard lesson to the current user base. I'd like to see this effort follow though, to whatever results may come of it, and for it not to get stuck on a single detail or two. Perhaps a few factions will split off in time with their own efforts, and I think that is something you might want to be prepared for.
Good documentation is a plus.
After the initial release of the following observation, I saw that the rectangles where quick to assert their position. Twm is much more rectanglar than KDE will ever be. Just trying to incite a little riot. Since then he has branched out into other small animals, including dashboard dogs and furbies. Today in his spare time he writes ramblings like these on his website .
