Back on tumblr, one of the features I liked was the auto-posting queue. Sometimes I'd see a bunch of posts I wanted to reblog one after another but didn't want to clog up my followers' dashes with a wall of fanart, so I'd toss them in the queue and it would space the reblogs out on a preset schedule. While being able to schedule individual chosts would also be a good feature, I like the set-and-forget convenience of the queue.
I really like this. It's especially good for themed blogs like "pictures of capybaras" because you can make a ton of posts in advance and then set it to chost post one a day, or one every 6 hours, etc. rather than scheduling them all like a social media manager.
