Describe The Feature Request Below

As a user I would like to sync read posts between my accounts so that I wont have to see the same posts when switch accounts.

IMPL: Save the read post IDs, periodically use the resolve_object endpoint to map the id of current instance to the id of the target instance. Only then use markReadPosts API for that instance with the ids that successfully got mapped, leave the ones that failed to map (If the post had not been federated yet).

We could also persist the ids but the ids should be persisted with its instance.

Wouldn't be too big a fan of this one, or any cross-account app-specific options that would potentially override lemmy's back end logic. I spose if its default off, then it'd be okay, but it'd still need to save those ids, then run a lot of mark as read on account switch, and clear ones that have been sent.

I just created a bunch of feature requests from c/jerboa

Ah gotcha.
