Support! As much as I post on free-adopt threads, even I get fed up with seeing them over and over on the main page. I am not sure how the site would handle storing an individual user's mute preferences, that's a lot of data per person, which CS already struggles with.
A less storage-heavy solution would instead be to let a user select the feed to view on the main page and check/uncheck forums to include in that view, or choose from a list of presets.
Editing to clarify further:
The current main page is like a stream chat feed. It's simply all posts, sorted by most recent, fed in and displayed, same as this page
https://www.chickensmoothie.com/Forum/search.php?search_id=newposts It's why you can end up seeing a post by someone on the main page recent posts even if you and another person have each other mutually blocked.
It would be more data no matter what to implement a custom feed- if the main page needs to remain uniform for all users to also be able to display the other elements correctly (oekaki, the news), then it would be nice to have that customization as another tab alongside the "new posts" // "active topics" feeds we already have when on the main forum navigation page.
There IS an unread/unanswered , but that is limited to no replies + topics you are already subscribed to, vs the request to mute/pick and choose and have a custom view which would allow for still seeing active topics/new posts while avoiding spam from a board you aren't interested in.
