Include A Search Option
If you have lots of separate documents saved on your device, locating a particular document can be a nightmare. You have to physically scroll through files hoping you don't miss what you are looking for and then have to start all over. Or you'll have to exit the app and search in storage.
A simple solution is the put a search function at the top of the open app, so users can type the title of the doc and have the app pull up all docs with that title. This should be an easy function to add. Other less popular apps have it and it's a shame that Word doesn't.
