Yes, because I think window title matching is easier for the user than the
windowid.
I'll extend this to regex as you stated.

Good point ! I also asked the question of how that trigger should be chosen
without testing.

I'll look in this. Maybe we can solve the problem in the reverse way, modify
the trigger in the configuration according to the known application
scrolling value. We have here a device dependent move property and another
application dependent one. I need to look and see what is possible to do.

Otherwise, I like the concepts here.

Thanks !
