How about adding a keyboard CW mode for the Maestro. As I see it, the M would display a keyboard on the touch screen that could be used to type CW.
I'm in the same boat.. when I use a keyboard my brain seems to turn off the traditional abbreviations and prosigns and I tend to send full words. Much more comfortable with paddles. I do realize there is a market for keyboard sent cw. Maybe if and when they activate Bluetooth on Maestro we could see a method to keyboard cw... and maybe a decoder or 2 kind of like in the K-line or some of the modern yaekenwu rigs so we can avoid going to a 3rd party app if we want.
