I don't think it is that important about who does what in what order. A great interface should allow everybody to develop their optimal workflows.
Although I am already a quite seasoned KT user, I have to admit I was expecting more from the new Thea interface.. It does remind me a bit of the Adobe Lightroom interface, which I consider great. So, you might be not too far off!
LR 3 beta is a free download by the way, check here: http://labs.adobe.com/technologies/lightroom3/
Please don't take the following remarks as being too negative (they're always meant to build up):
- I can't "read" (understand) the icons: too small, 3D background out of place, and meaning too unclear.
- LR has a great (and consistent across the modules) shortcut system. What's more, they're displayed everywhere, and you have all the time quick access to them using CTRL + / (or the Help menu).
- Big buttons drawing attention to constantly used functions / modules are of (visual) help.
- Same thing holds true for mouseovers / 1-line tooltips
- LR uses the same shortcuts as Photoshop to get more screen estate (TAB and F). Sometimes it doesn't hurt to use "established" shortcut and navigation systems (for example, letting people switch to the mouse navigation they use in the master program: Sketchup, Max, ...)
- I do like LR's folding panes (with hierarchy in size and markup of titles). This is already partly used in Thea (Scene panel), but not in the same consistent way.
I'll stop for now, don't want to cause a heart attack
Great basis though, now it's only matter of purifying a bit!
