Keyboard layout for remotes

Is it possible to make a addon to the keyboard layout?
It would be very nice to have a Http:// button on the layout. also the keys . and / would be good addition. Switching with a remote between character sets is somewhat tedious…

see image.

Or may be implement some different keyboards like on mobile : Default, URL, Email, Number.
But with that, each field needs a meta-type.

It could be made as a install feature. Choose keyboard appearance before installing…

This is a feature you should be asking Kodi developers for. This is not OSMC specific.
