Comment 9 for bug 1115376

After thinking about this again, I am in doubt that a generic control based solution will suite here.
I think this and follow up requirements are to complex to fit into a single data point.

So for now I would prefer a solution similar to RJs proposal in #2:

Extend the API to register a callback "OnCurrentTrackChange" that receives a Track pointer.
Provide an API to query the track metadata.
This API can grow as required and expose more and more Mixxx functions as required.

What do you think?

Has anyone fun and time to work on this?
This should be doable with some C++ knowledge and/or for an experienced java script writer anyway. I could give a helping hand.
