The CA MCU board without a display on it is quite small; it could even fit inside many controller housings.
There's at least one thread about running one "headless", if you are only using it's control functions and don't need the readouts, but I can't find it even after more than 15 minutes of poking around. :/ If I could remember who posted it it might be easier.
Anyway, the idea is that you setup the CA the way you want, then remove the LCD. If you have the buttons and serial connection to the computer still available, you can still make changes to the CA settings even without the LCD. If you put a socket on the CA's MCU board, you could even hook up the LCD when you need it, and leave it off when you don't.
If you add a BT module on the serial port, you can even use one of the apps developed here on ES to display the info from that port, on a tablet or android phone. I don't know all of the projects for it, or how many were finished, but there have been several started and at least one functional.
