I have long wanted better screen real estate use in KS. Now that a UI refresh is in the plans, I didn't want this to be overlooked; because it was created almost 2 years ago. "Old Timers" will remember it.
These mockups are constructed from an earlier KS version, so a lot is changed/missing, but you'll get the idea. Tabs are still used, as I don't think that the programming environment that Jonathan is using supports JQuery-style animation for accordion menus. If it does by now, that'd be great.
