Show HN: Script to simplify i3 scratchpad setup

I set up scratchpads in River and otherwise use it as i3.

  riverctl rule-add -title audio_term tags 1024
  riverctl rule-add -title audio_term float
  riverctl rule-add -title audio_term dimensions 700 500
  riverctl spawn "ghostty --title=audio_term --gtk-tabs-location=hidden -e 'pulsemixer; exec bash'"
  riverctl map normal Mod1 R spawn 'sh -c "riverctl toggle-focused-tags 1024; riverctl focus-view next"'

The example is from the config file, which is a bash script.

1024 = 00000000000000000000010000000000 in binary, that is, river tag 11; The scratchpad lives in "workspace 11" when not toggled.

`exec bash` keeps the window open if the program is accidentally exited.
