set -eu everywhere #

Set the useful shell options -e and -u in most of your helper scripts.

Not setting pipefail yet, need to do some testing. You find pipefail might lead to unintended failures because some programs within pipelines may fail on purpose, or failure is expected, etc. So need to test case-by-case.

help screens #

Most of your helper scripts now can -h. Please don't forget to do this in future scripts. Remember how many times you see a script in ~/.local/bin, open it and think, "what's this for again?" Add a help screen.

logging #

Most of your helper scripts now log messages. Since most of them are window-manager helpers, and your sway session is started with systemd-cat, all of these logs can be seen in journalctl.
