Not yet, no.
Personally, I'm using a combination of the app and being logged into my instance with a web browser to get what I want done (the app for browsing, upvoting and replying, and the browser for more 'back-end' stuff like creating/editing communities, and blocking instances and communities)
Came here looking for this. I loved browsing /r/all and using the block feature of Apollo to curate my personal list of things I want to see (or more often, things I don’t mind seeing more of). Being able to get that process started here would greatly improve my enjoyment of this platform.
