Feature description

Since the feed reload notification indicates which channel has been reloaded and includes a “Cancel” button, I think it would be a great idea to incorporate this information and these actions directly into the “What's new” screen.

Why do you want this feature?

I think it's important that the information and actions shared outside the app are also accessible within it.

Additional information

I've already added this feature for my personal interest, to learn how to contribute to open source projects.
By the way, I think that code inside org.schabi.newpipe.local.feed, could really use some refactoring.
