Hide the keyboard manually
Any iPad onscreen keyboard pops up, whenever ios thinks that it is necessary. But often I only want to mark and copy or paste text. But this force popup reduces my screen. So a nice feature may be, if the hide button has an alternate function, to reduce the keyboard just down to at last one key to get it back manually.
We implemented “short mode”: in landscape mode you may long-press the keyboard-away key to get a much shorter keyboard, which leaves much more room to see the app itself.
