With RIF is Fun, if content cannot be submitted, or the user decides not to post yet, they can save their text as a draft in local storage. Later, they can retrieve said draft, edit the contents, and post it, if they'd like.

Would Connect entertain the idea of implementing drafts? I think it would be even more useful with Lemmy, because most Lemmy instances are operated by hobbyists without SLOs, and I have observed problems with posting much more frequently than Reddit.
