clear known mastodon instances

[codl]

there ought to be a button on the front page to clear known mastodon instances from localstorage

also maybe a note the first time you log into a mastodon instance that isn't on the default frontpage list that "it's been added to your frontpage" or something

does it make more sense to have one "reset known instances" button, or a "clear" button on each instance that isn't coming from the server's most popular instances list?

I see more of a use case for the latter, "I logged into forget from an instance that I don't want people looking over my shoulder to see each time I log in again". Whereas the former is kinda equivalent to clearing site data in your browser, since you're probably logged out when you see it anyway. And I can't think of a good use case for it, but please sound off if you do.
