I would be in favor of adding just one section back because I agree it is a little confusing to have two sections like this, because if you think as a new user, which one is the actual like button? It’s easy for us to tell because we’ve used the software but new users might not know that.
However, I would like to see it retain the popup instead of the original grid which was limited to 200. I think the popup works good (even if there could be more features to add to it, like said legacy grid view)
