Consistent, Excellent
For several years Documents has been my IOS app for filing all the emailed PDF files I receive as a Master Gardener, mostly on my iPad. A few taps and done. Name change or new folder, a few taps and done. Need to go online from the app? Yes, you can.
Cloud storage makes it available from everywhere. The great thing is I also can see the files from my Mac desktop!
