I waited a decade & half? for an edit button on a major corporate media silo (#Twitter). When it finally arrived it required a monthly fee, and by then I had already left some time ago!
There are tons of clever people making things all the time on the #Fedi. This is part of it's strength. The #Fediverse actually innovates much faster and also in more interesting iterations and directions than the monetization driven corporate social media silos. Decisions made for users, are better for users, than decisions made for shareholders.
