I would like to suggest these features:
1. Button on main screen to activate auto-focus. This button should be easily accessible and navigate to by using just the trackpad even when the image is totally out of focus. This is useful if there is a problem with the AirMote (eg. lost, no battery, damaged, etc).
2. Function key on keyboard to activate auto-focus. This is useful for those of us using keyboard instead of the AirMote. I suggest a default mapping of Ctrl-F1. If possible, an option for users to customise to another key would be even better.
Please vote if you think this is a good feature to have.
