What about an audio only record mode? It would be cool to be able to disbale the video to increase the storage size and then use the HVX solely as a digital audio recording device. I know most people wouldn't put that feature to use, but it would be a nice option.
I would like to add: useable volume control.
Those little wheels where I have to press my finger on them and then to guess where the pointer is, are of no use. I had to glue proper controls on top of the wheels for better control.
