Is your proposal related to a problem?

Currently when saving a post and trying to view it on the saved tab, all the post sort options are available except for the ability to sort by the date/time that you saved a post.

Personally this was confusing for me as I would sometimes save posts, switch to the saved tab and not see that post unless I scrolled down for a bit. It made me think at first glance that the save didn't work.

Describe the solution you'd like.

Adding an extra sorting option, "Saved Date" or worded however differently that would order posts by the date that you pressed the save button on a post. it would make it less confusing at first glance, at least for me.

Describe alternatives you've considered.

I don't believe there's any way of sorting the saved posts like this at the moment, from what I've been able to see.

Backend issue, and it probably should just use the published on the join table.
