Hi Michael,

Surely, I knew about it. But other part of described palette handling after clicking on button lying in the palette "marked as rarely used" is important part as well. It was a crucial thought of my previous reasoning. Now, palette handling can be characterized as self-expanding/other-collapsing. What I meant it was to make a things upside down (for less commonly used tabs/buttons) - i.e. self-collapsing/other-expanding_to_previous_state to restore it.

I really hope the scroll bar never appears to me... hehe... It would imply there is something wrong with UI - too many commands, palletes or something like this...
