In the next release, the information icon that shows up next to files and folders will be replaced by a much clearer contextual button. The menu that got triggered used to fill out the entire screen, but now it'll be a simple pop-up on the bottom of the screen with a list of actions you can take.
You'll also finally have access to your Trash with all of the files that you had previously deleted. Restoring and deleting files and folders forever will finally be available from your phone, instead of having to wait to get to a desktop computer to do so.
Left: New contextual menu Right: Trash access
And lastly, there's a small visual change in the way shared files are displayed. Instead of simply using the document's icon, files under Shared with me will have the avatar of the person who sent them to you, layered with the document's corresponding filetype icon. It should make it easier to spot documents originating from the same person or to browse a long list of shared files and folders.
The update doesn't appear to be live in the Play Store yet, but it is supposed to be coming to everyone in the next three days. We'll keep you posted when we have it on APK Mirror.
