I use take lanes for what I thought is their intended purpose: To record/write different parts to see which one(s) I want to keep. But when I use the staff view to look at the current take, guess what I see: ALL PARTS at that particular location in the composition. This just...blows.
So, the way I see this functionality needing to work is by letting a user click on a clip and only see that clip's notes. That said, it might also be beneficial to give the user the option to view all non-muted take lanes.
