You don't see full quality after zooming in. Also add mobile push notifications for when someone shares a file in a shared folder. Make commenting on a photo or any file (like PDF) possible without having to select a rectangular area. Enable mobile push notifications when someone comments on a shared file. App doesn't refresh by itself.
