i too am hoping for this to be added, i installed it as standalone and added short cuts but the radio is unreliable and mostly did not work, it opens ok, buttons are responsive but that was as far as it went
what do other people use for internet radio, im not interested in fm or rds as i live in a foreign country but would like to keep in the know with my own, i know tunein works with kodi but kodi is a pain in the butt and i would like a working shortcut on the applications page
