Feedback²
Dear website tool together folders; folders,
I came across something that annoyed me a bit and this was when the keyboard was shown on mobile devices it shows the top and sometimes lower bar of the browser even when in full screen mode.
I only needed a numeric keypad, so I created my own to avoid this; I did this because on iOS mobile devices, I could not hide the onscreen keyboard when I wanted it and because of the earlier mentioned.
Therefore, my feedback because my rambling goes on and on again:
I would create your own keyboard element; this would avoid this all and would make it easier to use on different operating systems and it would give you more control over showing/ hiding and such.
