I found another feature that Mastodon does better than the bird site. I made a mistake in a toot as I am wont to do, and I had the option of "delete and redraft." I've always been against an edit button on the bird site because bad actors will get likes and RTs and then edit to make it look like people agree with other than what the current post says, but keeping exact words is great. On mobile, copying and pasting doesn't always work.
