Since there is no way currently to quickly and easily subscribe to a community from the search menu, sharunkumar (not me) added a way to do that in this pull request.
There are 2 poosible designs that are consistent with UI of voyager so I will comment the images of the design below. Upvote the design that you prefer. Please refrain from downvoting.
Also it would be appreciated if the mod (@aeharding@lemmy.world @aeharding@midwest.social) can pin this post (for a day or two) to ensure that it reaches most members of the community
It is not my design. I just gave some inputs. All credits for the design and the pull request go to https://github.com/sharunkumar
