My mastodon wishlist atm:

* turn off boosts by user (boosts are great but some people are just boosting so much that it's overwhelming and I have to search for the toots by the people I actually follow in my TL)

* finetuning notifications (for example decide to still get notifications from muted users)
* import/export your own toots
