Over in the other thread, we talked button window issue, I have one more.. o)
When in customize mode, I often use CTRL-LeftMouse to drag/clone a button to then immediately change it. After the drag-clone, the two buttons have the same name, I would like the clone to have a different name with a suffix like " - copy". Most of the time I open the original and the cloned button and you never know which is the one you want to keep untouched and which is the new one to be edited. Both windows appear at the same location, hiding whatever button was opened first - so you'd think at least, because the button windows switch "plane" or z-index randomly at times when opening multiple.
If the button windows would offset slighty when opening, you would notice a switch of the windows more easily (if that actual issue is hard to be fixed, we tried in the past iirc), an offset for a new button window is welcome anyway. The suffix " - clone" would make even clearer which button is the one to edit (you'll probably change name anyway, so adding " - copy" to the name would not hurt).
