Enhancement: Dynamic Subscription Lists

Currently the subscription list is static. It appears to be in alphabetical order. It would be nice if the list was sorted based on the most recently updated channels. This will be extremely useful for users having a large number of subscriptions.

This would be neat but I think the list should still be alphabetically sorted by default. At the top of the list there could be a select allowing you to choose between Alphabetical and Recently active sorting order.

@Larivact Yeah, this is pretty much what I was thinking as well. I think both options would be great.
