Suggestion - drag-down to refresh folder contents
You may be working on a more comprehensive solution, but I noticed a reflexive action I have when looking for my newly uploaded samples in the import folder. It now takes some not clearly understood series of actions like returning to the performance view, waiting a bit, going to a different folder or something to refresh the list. I can also re-scan the database.
I use other apps, especially the mail client, that refresh lists when you pull-drag the list downward when it's at the top. (sorry, can't explain it better than that). I notice the first thing I do when I'm not thinking and something isn't showing up yet is to pull the list down. Maybe this could be a good quick way of refreshing a folder list.
No biggie - just a thought.
