Sounds like they did add controller support according to recent reviews. Just picked this up to give it a try on the deck tonight!

I asked bing because I miss using I3, and here’s the short version of what it gave me.

bindsym --release --no-repeat $mod+Shift+q [class="Firefox"] nop

Might have to fiddle with it, but then dropped the command into a new chat and had it explain what it does, and it figured out that it should use nop when Firefox is focused.

So, hope it helps some. Now I’ll go think about getting back to i3 somehow.
