The existing track information panel allows for up to 7 fields, which I've already used up. Sure, they can be configured to contain a lot of different information but if you're already displaying the artwork too, it gets kinda crowded.
An additional panel, stacked as a tab, which would only display configurable fields would allow for a lot more info, such as involved people, composer, lyricists and so on. Seeing as the panel's already part of the software, I was hoping it wouldn't be to time-consuming to add an additional one.
