I’d love to have plex too, but for now plexbmc is an acceptable solution. https://github.com/hippojay/plugin.video.plexbmc/releases
Themes like Amber, Nova and Black Glass Nova have a go plex setting that swaps the kodi main menu items for your plex main menu items. Set Amber to have a vertical home screen and it ends up looking a lot like plex. It isn’t as stable, but not bad, probably better than dual booting or card swapping.
