I have a couple of suggestions to the Live View window:
- Add shutter dropdown (DSLR users) or exposure float inputbox (CCD users)
- Add ISO dropdown (DSLR) or GAIN (CCD) integer inputbox
- Add a button which would allow to activate an image overlay such as a cross-hair (X, +, bullseye, etc)
The selection (DSLR/CCD) would be automatic based on the driver used.
