apparently repointing your Kodi media library to a new location isn't quite as straightfoward as it was with Plex. Not looking forward to manually editing a giant exported XML file & then attempting to re-import it.
"why do you have both"
well Kodi is really good as a UI running on a computer. I can also make it launch Firefox, Chrome, Parsec, Steam, Retroarch, and basically any other command I can run on linux. I actually only installed Plex because it had a functional web interface, since the Kodi web interface basically doesn't work for anything that's not already in an HTML5 compliant format (and even the files that are are sort of a crapshoot)
