I feel like the microblog feature would be more useful if we could get a separate feed/filter that doesn't include the tags of magazines that you're subscribed to. For example, I'm subscribed to /m/fediverse because I want to see the threads that people post here. I don't necessarily want to see every mastodon post tagged #fediverse, though.
It also looks like we can't subscribe to a tag by itself, without subscribing to a magazine that includes that tag. So yeah, some more separation there would be nice.
