Allow adding custom feeds as tabs

[opusforlife2]

Is your feature request related to a problem? Please describe it

The What's New tab is a feed of all your subscribed channels. Currently, you have to go to the subscriptions tab and tap on a channel group to see its feed.

Describe the solution you'd like

Just like you have the ability to add a kiosk as a tab from a list of available ones, you should have the ability to add your custom feeds as tabs.

Coincidentally, this would make Newpipe similar to the Slide for Reddit app in how subreddits are browsed. (Though that's not where I got the idea. The similarity struck me just as I was writing this.)

How will you/everyone benefit from this feature?

Easier access to dedicated feeds. The default feed you see when you open Newpipe can be a custom one.

I'm wondering if anyone has considered this issue, it would be a great feature.

I have a detailed writeup on how I imagine it would function over at #5209.
