If the problem is finding the right track to modify then I can probably make that easier without a lot of work (which re-working the whole layout would require).

In the tree I already include the CodecID. In the same spirit I can incorporate more information, probably in the form of real columns and not just as text in the first column. Track name, UID, codec ID, default track flag, video resolution/audio sampling frequency & number of channels come to mind.
