Sort suscriptions by last update

[racuna]

Hi, I have NewPipe installed since a lot time ago, mostly to listen music. But since the official app becomes unusable (two ads before video starts, one ad every 3 minutes, and one ad at the end), I started to fully using NewPipe instead of Youtube.

One thing I noticed when I imported my subscriptions, is that a lot of them are pretty dead. And, when I refresh the "What's new" list, the app start to read every subscription (about 460) one by one.

Describe the feature you want

It would be very useful to sort them by the last time they update their channel and start to delete every channel who doesn't update since X months or weeks.

Optionally, also describe alternatives you've considered.

Also, in the "What's new" tab, maybe would be great to unfollow a channel directly from the "long tap" menu. Which will be useful to declutter subscriptions as well.
