Feature description

In case we have lot of subscriptions, they should somehow be colored from a channel they come. (Maybe colored line to the right or something not too intrusive.)

So, red would indicate channel from YouTube and orange would indicate channel from PeerTube.

Why do you want this feature?

Where I use the app, some services are not available, so to know what not to run.

Additional information

Not to confuse with custom colours requests.
