Follow certain channels / Broadcast any channel /Mute all except

Hey, so the title has different option to an issue I am having but non seem to implemented. Right now I am having an issue that I am in many different channels some that are really big aswell. I myself am only intrested in 1 or 2 channels and would still love to get notified about those. I know I could manual Mute every Single channel except one but this is Labor work times 10. Here would be my Suggestion the first one would be my Favoriten and practical one:

- You should be able to follow certain channels and have a dedicated place for followed channels. No more searching through your Servers (of course you should get notified for followed channels even though the Server is Mutes)

- similar to the Broadcast Funktion could happen to All the channels. You cann see what's going on in your Favorite channels in your own Server (replying with this Methode would be not so easy, maybe if you reply to a broadcasted Post you have shortcut to the correct channel

- last but not least the option to Mute whole channels but you can define channels you do want to get notified
