CLIPBOARD HISTORY PLEASE!!!

Its one thing that I can't split screen apps on iphone, but why the heck is ios the ONLY os I can think of that doesn't have a copy paste history. Filling out forms on the iPhone is basically impossible without it. Some websites just close and lock u out the second you change apps or tabs to copy or look for the info you need to add. It is ridiculous we can't have this feature on iphone/ipad. PLEASE ADD CLIPBOARD HISTORY!!!
