Multiple icons with parent folder display improvement of child folder's status.
When a file or folder is syncing under a parent child (1) its either displaying the could icon or something else. (2) It would be better to display the sync icon marking that upload is happening UNDER that folder. (3)
There could be multiple icons next to eachother. The icon that represents the folder itself, and the status of files under that folder. This would only apply to folders obviously.
