@feditips I can't test it, because the server I'm a guest on is not yet on V4, but in 'Subway tooter' for Android there is an option 'Followed tags'

BTW: is there a reason I only see Tusk(y?) mentioned as Android app. My experience with Subway is very positive - I like it a lot more than the Tusk-thingy (for one: more columns - Tusk limits that to 4/5 I believe)
