Often when I want to find a community, I'm just using the search function. It's great that communities show up, but why can't I interact with it? There are no options and it's just a list, but a list is pointless if you can't do anything with it. Maybe tap could take you to the community and there could be a dropdown to subscribe? This is a rather frustrating user experience as I was used to just typing a community in the rif sidebar and getting to the community I wanted.
