Feature request: Stateless operation of Show Desktop button
The Show Desktop panel button currently saves current windows' states when clicked on, which is also indicated by the color highlight below the button. The windows are then restored to the previous state on second click and so on.
Certain users prefer stateless operation, meaning that the button doesn't go into an activated state when used, but it simply minimizes all windows. If clicked on when there are no windows shown, then it restores the minimized ones (with the most recent one selected/activated). In this mode of operation button highlight is useful only for button click feedback.
The Show Desktop panel item currently has no settings window. This proposal would require it for setting the operation mode, but it is not the only feature request that would need that. For reference: #517, #526 and #551.
