I did radio stations in Arcade Music Box, but was not needed that in MultiFE (MultiJuke). Hence I did never all that.
I could add these 2 extensions for the Explorer Library system in MultiFe, if I wish to do that and then radios would been added in MultiFE and could shown as own library.
It would been more for to do a real Radio Library more automatic using a exists server based list.
I dont have tabs like E-Touch, but can been any type of library, but I diddent think its a popular request, so I should look on that (even I have 2 music projects by now).
