Thanks for hijacking my thread, Andrew 😉 NHNF
Btw: are you aware of the 'wmctrl' program/command? I'm not sure whether it can help with your cause (mostly due to the fact that I don't grasp it), but I thought you'd might want to give it a thought or two.
Glad to read about your content with 35. Be happy with it. But I've issued several concerns, which, to my thinking, are very valid.
