Add a favorites list

[AndrewTheWookiee]

I follow a lot of channels, but have a few that I consistently watch, so it can be annoying to scroll through a long list to find them when they're live.

An extension I used that hadn't been updated in a couple years and just recently broke due to Twitch's new api had this feature, and I would really appreciate it if it was possible to add.

Thanks :)
