Toggle keyboard visibility and resize the layout

Is it possible to hide the keyboard when not needed? While reading the saved notes, when the cursor is placed, keyboard occupies good amount of screen space.

On Android (Sony here) it's easy to hide the keyboard with the usual OS nav buttons, but yeah, the definition does not resize when it's hidden. It'd be nice if it expanded to occupy the bottom half of the screen when the keyboard is hidden.

This can enhace by when user touch to result panel (scroll to read meaning) , the keyboard auto hide, and when user touch to editor to type word the keyboard auto display back

@kiemrong08 It's funny since I did exactly what you described in my PR #21 . It would be great if you can try it and give feedback while we wait for @zehfernandes
