The extension is called Burn-My-Windows and I always look forward to it when booting into GNOME because it feels so ✨fancy✨

I stumbled over Gradience just yesterday but I tought it was archived sometime last year, is it still working accordingly?

Unfortunately not :/ But I do have rainbow-gradient window borders.

I suppose you’re mainly concerned about LibAdwaita-Apps?

I was surprised to learn that

• a) macOS only recently added Left/Right-tiling natively (without extensions, just like GNOME does)
• b) they leave gaps when you tile them so that it looks like you messed up the tiling somehow

You can use backreferences \1 \2 etc. but you can also give them names explicitly.
it looks like this: (?<name>inner-regex)
Some flavors support it, kotlins doesn’t apparently.

I don’t actually know whether POSIX grep would support named groups :o
