This windows rules feature seems to be bug ridden. Yesterday I struggled with it all day. Rules were not being followed properly, were erased mysteriously, etc.
I like KDE a lot, but this part of it needs work.

Also don't forget that rules can interact with other rules. For example, window size interacts with all of: "fullscreen", "maximized", and the "geometry" options (commonly set to more than 1 pixel for terminals).
That said, I am really not a fan of the recent UI-pessimization of the settings screen to require you to type out the setting you want rather than have tabs listing all the various options in a discoverable manner.
