I like that but I don't know how to do that with #gnome or #kde unfortunately.
For the three fingers gesture, I guess it was not your main question and there is a lot of answer.
I didn't try to create a window rule with KDE, maybe it is possible to achieve that actually!! ( that's a #question for someone that use #plasma )
