Multi-select to delete feeds all at once

[curiousdreamer]

Is your feature request related to a problem? Please describe.
Every once in a while, I do a purge of my YouTube subscriptions, and it's a bit hard to delete them one at a time, so having a multi select to delete would be nice.

Describe the solution you'd like
It could look like a circle next to the add button in the Feeds popup that when you select, turns into a checkbox circle, where you can then select multiple feeds. You can then show the toast notifications at the bottom right where they usually are, but for multiple feeds.

Describe alternatives you've considered
Deleting them one by one or deleting my account and making a new one if it's a lot of them.
