What is one small UI tweak that would instantly fix your daily feed experience?

I like browsing discussions here, but the alert setup forces you into an all-or-nothing situation. If you reply to a post, your notifications get blown up but if you don't stay active you completely miss updates from topics you actually want to track.

Having custom controls to mute specific comment threads while subscribing to broader discussion tags would make the site so much cleaner to use daily.

Curious if there are other small interface bugs or missing settings that constantly bug you while using the platform?
