In the files pop-up window view, please create a button that will open a folder. When I am using my iPad, I am unable to open a folder. Tapping the folder just makes the pop-up window enlarge. I am also unable to move down the list past the first few folders in view. If I could click on a folder and then have a button for "next" and "previous" that would move me through the list of folders. Thank you.
