grouped windows should open last window on click
Submitted by Raphael Bosshard
When clicking on a grouped windows button, a list of the windows in this group appears. This is annoying when switching fast between windows. Instead the last active window in this group should be brought to focus.
Alternative: never group windows of the same kind as the active window. Instead goup as soon i give focus to another window. Ungroup on click and bring the last active window of this group to focus.
