I am trying to make a tool-window (and splash screen) floating with for_window, but want the main window to act normal (non floating). The application is DDD (Data Display Debugger).
for_window [class="Ddd"] floating enable
does work. Is it possible to append something like:
Note the ! before =, to negate the instance.
What I try to achieve in words: Make all windows with class="Ddd" floating, EXCEPT where instance="command_shell".
PS: I have got the proper definition with xprop -spy.
