Bug 394603

Set "Recently used" for "Sort order" in Task Switcher options and then:
- open 3 windows (A, B, C) one after another
- minimize window C and windows B will become active
- press ALT-TAB and window A will become active

The desired behavior is to activate window C that was minimized. It is how Windows, MacOS and even Gnome will behave in that situation.

I understand that it could be done intentionally, but then could you please implement a checkbox in Task Switcher options to make it optional.

I am not alone asking for that feature. Here are some discussion threads:

Currently I have to apply the below patch and recompile KWIN every time I install KDE.
