I used that combination, too. But I have settled for only the useless gaps extension for now. PaperWM was behind Gnome version too long and now I have seen there is Niri getting better and better. I will switch someday, I guess. It has the same concept as PaperWM, but is a scrollable/linear WM from the ground up.
I bookmarked this one, because I didn’t get this one and hope I will understand it in the future.
