There’s many, but the most improvement is plex with the whole servarr stack automating nearly everything behind the curtain. Plus notifiarr with trash guides library improvements.
Besides that, home assistant also improves my life quite a lot.
I’m running quite many apps. Just some:
Linkding to collect bookmarks Mealie to collect recipes Nextcloud syncing to photoprism Syncthing to backup the phone on the fly (downloads, app backups, GPS logs to replace Google time-line)
I encountered ddos attacks on my entry/relay node. So I stopped it again.
Right after the node was fully provisioned and registered in the tor database it started. Had internet crashes multiple times a day.
Give it a try, better not an exit node, just relay or entry and have a look on it. It’s always good to help the tor network in any way. But be aware of what I encountered.
