Submenu on homefeed swipe right

[lvndr-dev]

Is your feature request related to a problem? Please describe. Artemis opens on the home feed with all subscriptions by default. This is as expected (though should be customizable to other sources such as hot posts from the fediverse).

Swiping left to right on this screen currently does nothing. Are there plans to have a list of sources appear on this interaction?

Think: selection of popular, homefeed, or subscribed magazines.

I personally would prefer this over the current means of the 'Home' text dropdown for subscriptions.
