Better yet, why not allow attachment of any files.
Ever better, why not allow attachment of any files to the track notepad. That way you could attach patch files to audio tracks for the device that you recorded on that track, for example a guitar amp modeler.
Any improvements should be made in both the Track & Project Notepads.
And while they’re at it how about a Notepad Track for timeline dependent info. I use a Marker Track for this now, which is OK-ish. But having a Notepad event that could contain text, pics, etc. would be pretty useful.
