Qtile... the default bar is really nice to use and if you know a little python every aspect of the WM is easy to hack around in. Docs are great too.

Use mailx along with a .mailrc file? Once .mailrc is set up it should just need:

$ echo 'is this working?' | mailx -s Test

Not sure exactly what .mailrc needs for gmail but there are tons of guides out there.

Probably doing that anyway

you dont say the o/s but if the pkg manager works, or you can add a statically compiled version, you could force reinstall all pkgs

beets.io with the discogs plugin has never failed me. If its on discogs you will get tags

purelymail.com Cheap and never had a problem wirh them.

Who owns the mounted files and what are the permissions? $ ls -l /path/to/mounted/sdcard

Nothing to really fix because thats the design. In userland you can do anything, system wide needs elevated credentials. If you don't want the password prompt, look into aliases and sudoers/pkexec

Loguru... dunno about lightweight and fast but its definitly easier (for me) than the standard module (and it is colourized)

Antennapod also has an option to skip the first X seconds of a pod and the last X seconds. It's really useful when an episode starts with 3 minutes of ads.

Its easy with Jellyfin and the config will tell you if its set up right. You can either go directly to the Jellyfin port or thru a reverse proxy but either way you're exposing ports. I ran mine behind docker so I could easily keep everything up to date.

Supports musl on every architecture I have. ARM, AARCH64, x86_64 - no problem.
