This is a very important suggestion which would make MediaMonkey a really serious music manager:
MediaMonkey lacks a multi-line field wich contains clickable links to files (or web-pages) related to the song. For example, as a musician, for many MediaMonkey songs I have the sheet music as a PDF file somewhere on the hard-disc. So it would be very convenient managing these relations in the following way:
1. I drag a file (e.g. a sheet music PDF file) from Windows Explorer to this field (let's call it Links field). Then another file related to this song. Then a URL from my web-browser's address-bar.
2. In the 'Links' listbox now there are all these links to files and web-pages, where the Internet links are blue-underlined and the file-links maybe brown-underlined.
3. Now the next time I open the Properties dalog for this song in MediaMonkey, I just click on one of the links to open the file in its associated program, or the URL in my default web-browser.
This would be so HELPFUL!!! It shouldn't be difficult to implement. I am a seasoned Delphi programmer myself, and I could implement this feature (including debugging and rock-solid testing) in just one day!
