Hi Steven,
Discovered MB quite recently, and really think it as a terrific audio player, thanks a bunch for this!
One thing I miss about radio support, is the capability to set the radio web site in the settings of a radio, indeed some radios don't send the playing artist name, and sometimes going to their web site you can get this information. Along with the capability to set the URL, a way to go to the web site should also be provided: a possibility is to have the content of the to-be-created "Web site" column clickable. But I'm pretty sure you'll get other better ideas.
TIA
