It would be great to mute entire categories so I never have to see them here. I sometimes read stuff here that I wish I would never see and it’s always in categories that are completely irrelevant and uninteresting for me.
Muting specific users would be great too.
Also muting certain phrases would be very cool.
I’m getting too old for some of the nonsense here sometimes.
Thx,

Common dude, give me another chance… I promise to be better! 
One can mute entire categories under Preferences > Categories and ignore/mute specific users under Preferences > Users. The ignore feature doesn’t really work though, as topics/posts from these users still appear in the feed/topics.
I was going to point this out.
Indeed, almost forgot. At least muting categories works as (I) expected. I see one can also mute tags now, that might help @gustojunk further feng shui his feed
