I've only run the live CD so far. Like the look, but I have a very simple question: is there a way to add tooltips to the icons in the panel that identify what they are? I couldn't find anything on the CD but am not familiar with the system, so probably missed it.
Also, is it correct to think of the "shelf" in E17 to be equivalent to the panel in KDE? Or is it more like KDE4's "desktop activities"?
