What if there’s another plugin with that name or slug from WordPress.org
RepoMan always displays it’s own list of plugins from the json file first in search results. We played around with a few different approaches, but I think probably we will not remove duplicate namespaces and just allow users to choose which plugin they want.
The only issue is if you install a plugin, fail to delete it, and then change your mind and want to install another plugin with the same namespace… in that situation you have to delete the old plugin first.
