Bring back this feature of the desktop service
I follow a large number of streamers; mainly because my preference for what type of game or content I'm 'into' at a given time changes. I might be really into Rust for 2 weeks so I want to see people I follow who play that, but then I might pivot into wanting to watch a lot of the streamers in OTK and will want to check when they're live instead.
One of the features I saw recently (which I assume was being beta tested?) was the option to pin/favourite certain streamers you watch all the time.
I see this as super useful from two angles. Firstly, I watch TrainwrecksTV pretty much every time he goes live and leave his stream running for many hours whilst I work or game - so he's a streamer I'd love to be able to easily see "Train is still live" 9 hours into his stream right there at the top (in a way 'going live' notifications only do the once). Secondly, in that Rust/OTK example I gave, you could switch out priorities whenever you want as a viewer.
I can't imagine this would be particularly difficult to implement, so I'm guessing either the favourites got negative reception or you just want to move in another direction? Either way - wanted to suggest it as I loved it when it was a thing for that brief period a few months back.
