Questions about Lemmy

Is there a view where you can navigate to the sub-lemmies (what are those called btw?) that you are subscribed to instead of just finding them in the huge list? Also is there a way to get a feed of all the posts in subs you're subscribed to like the Reddit home page? Also, is there like an r/all?

There's far to many subs right now and it's hard to find what's being posted.
