There is a new implementation of the original TeamMentor UI writen using the jQuery UI.Layout API (already used on the control panel).
This makes the gui much more customizable, introduces the colapse of panels, and solves a number of IE css problems (which existed in the previous version).
This layout is now pushed to GitHub, can be accessed via http://127.0.0.1:12345/Aspx_Pages/TM_3_0_with_Panels.aspx and is a screenshot of what it looks like:
