[Feature Request] A way to favorite a sublemmy (subreddit?) without subscribing

I like some communities easily accessible but I don't necessarily want them on my main feed.

An example is politics, I like to check in every now and again but I don't like seeing it all the time as it gets my mood down. And I'd prefer not to have to search for it when I want it.

Reddit Sync (my preferred reddit app) has this feature and I think it would be a great addition.
