[Feature] Temporarily hide read posts

[Maxplosion]

Hi!

A feature request to add a button to temporarily hide read posts for the current session.

Example: 10 new posts on the sub (or front page), I read 5 of them, so 5 unread, 5 read, press button, only the 5 unread are left and shown, rest is hidden. If I now manually reload the subreddit page (or open and close the app) all 10 posts, where 5 are marked as read and 5 are marked as unread are shown again.

In the current implementation with hiding read posts using the settings switch makes it so if I want to reread a read post I have to use the toggle in the settings, search the post, read the post and activate it again in the settings - a rather cumbersome workflow.

Thank you!
