Following up on this 5 month issue as well. I have just upgraded to 5.1 (I took a chance!), and found out that the edit and delete icons does not show anymore, which is great!
But if I disable the upload, I cannot still navigate down into subfolders. If I put the allow upload back to true it works to navigate into subfolders, but then the upload also shows in the dialog box, which is not ok.
Any news around this?
BTW, 5.1 looks promising of what I found so far. I will put it to the test soon.
