"Back to parent folder" Button may be Redundant and should not require a Double-Click

I think this button might be pointless since the user can just click the associated breadcrumb. But you could disagree with this, some might find it easier to have a dedicated Back button.

However, this button should NOT be a double-click. This is rather unintuitive. The first few times I clicked on it I just thought it didn't work.
