Feat: Hide viewed and voted posts

[LoveIsGrief]

Is your feature request related to a problem? Please describe.

When browsing the feed, it happens often that the "hot" or "active" feed stay the same for a while.

Describe the solution you'd like

Lemmy provides the option to hide posts that have been viewed or voted upon. It would be great if mbin had this option too as well as a "hide" button.

Describe alternatives you've considered

What I currently do is never go back to page 1. Just keep going down the pages and opening the posts in tabs. However, sometimes I come back after restarting the browser or opening mbin and only the first page has new stuff, but the next ones have all been viewed.

Additional context

None
