Hi,
All that should be possible through Yak, Rhino’s Package Manager.
That said, there aren’t many 3rd party plug-ins that have enabled the use of Yak at this point. Reach out to the authors of your favorite plug-ins and ask them to look into this.
@will, as far as I can tell, the UI doesn’t expose uninstallation but I see that Yak CLI has yak uninstall.
