Woo, edit button just went live on mastodon.online!
Apparently it will be rolled out to all Mastodon servers in the next update.
(This only works if you're logged in on the website by the way, not the app.)
@feditips mastodon.social has this already. Maybe mastodon.social got these features because it's Gargron's instance?
Yes, mastodon.social and mastodon.online are both owned by the Mastodon developers. They often use them for doing final tests on new features just before release.
