One great feature Diaspora could have is to "turn off comments" for certain users' posts in your stream. There are a few I don't mind following, but I could do without all the crazy mouth-breathers "derp derp derp"-ing on every post.
I have think it would helpful to be able to "turn up and down the volume on" on some accounts - I don't want to mute, but for example only receive 3/10 of their toots. Any 3 would be fine. This feels like it would be easy to do and really useful. Please do let me know if such a thing exists... :) #featurerequest
Wanted: Not quite a search feature, but a "Fetch" feature -- When I see an interesting post on your instance, be able to fetch it into my instance so I can reply to it. !GNUsocial #FeatureRequest
