Few quick Mastodon tweaks I like:

* Settings > "Enable advanced web interface" is Tweetdeck and works really well.

* In your notification column, turn off all the "Play sound" toggles and turn on the "show filter bar" to be able to see favorites, follows, etc. by type.

* The web app is good! The official mobile app's not bad, either. But there are a lot of app options with different flavors worth trying out. Toot is popular on iOS. On Android, I use Yuito: https://bit.ly/3jjtzif
