As it has been stated before, I miss a good selfhosted mobile MDM. Maybe one day, Fleet will be able to do that!

This is a nice, but I also would love to see a digital music marketing tool (like linkfire, amplify, where you can presave your music to Spotify/Apple Music,...). There is literally no project for that (yet).

I see this post more open to company selfhosting, whereas the post you mentioned focuses on homelabs. I've got both homelab and company servers, and the selfhosted needs differ a lot.
