I have Kodi on my stick but apart from using it for iptv & 1080p movies I cannot findon Terrarium or MovieHD I mainly use apps.
Poseidon,Bennu,Bob unleashed,MaverickTV,openload,UK Turks,openload,Risingtides,Deathstreams,Falcon,Suprabox,The Pyramid,Wolfpack,Elektra Vault,Covenant,Nemesis and Elysium are all the Kodi add-ons you need and even then you would rarely use half of them & there are a few for just Documentaries and Music.
