I’ve been using this beta for a while, it works fairly well and should be close to what is soon to be published by @nate. NLP 3.0.2 and the new version can co-exist, at least they do on my Macs.

Moving a plugin the plugin folder enables the respective plugin after a restart of LrC.
I often put all plugins in the folder. I can then switch them without restarting LrC.
