Current problems: LCD stays lit and powered while the PC is turned off, possibly due to wake on keyboard/mouse being enabled..
I'm planning to add:
- a rotary encoder for navigating menus
- keeping track of stats like words per minute
- switching backlight power
- arduino reset button
- morse code input?
Long term i'm aiming to have the arduino connected directly to USB, but i'm not sure if it'll cope with the extra load..
