Florence is very flexible in customizing the virtual keyboard. You can change the style of the buttons and the keyboard case, and the type of the keyboard itself (condensed or complete). The use of this keyboard is very useful when working with TouchSreen, or when a limited number of keyboards.

Florence stays out of your way when you don't need it: it appears on the screen only when you need it. A timer-based auto-click input method is available to help disabled people having difficulties to click. You may also check the new efficient ramble method.
I'm going to buy a tablet and put Linux there. Maybe I will install this virtual keyboard. I think it will be convenient.
