Add an option of full "slim keyboard"
I would like to suggest to add an option of a slim keyboard. On Android, I currently use Hacker’s Keyboard (some images here. HK is quite good, but still is not perfect, if you use nearly all the keys.
What I would like the virtboard to look like is something like this:
Some notes:
(1) F1 to F12 could be hidden (we could have some kind of toggle to access these keys).
(2) Above Left and Right keys and below Right Shift, there definately should be some space. :)
(3) Left Ctrl should be the leftmost key.
(4) There could be an Fn key, which could be used to access the NumPad (like in HK).
(5) [Low Priority] Use might configure the image of Win/Meta key.
(6) There should a bit more space under the ESC and F1 to F12 keys, and left from Home, PgUp, PgDn and End keys.
(7) Context menu key is sometimes also important. :)
