I think it'd be great if when I view the link of a post, whether it be an image or whatever, if that marked the post as read. Which would go great with the already existing feature to hide read posts.

Additionally, a button on the main view to see or hide read posts would be cool too but not as important.

Keep up the great work, I love the app!

Edit: it looks like there is already a setting "Mark post as read on image view" that I didn't see. So looks like that works. But it doesn't make the title of the post change from normal to "read" like it does when you click it
