one very important (IMHO) request: get a decent API (dbus or whatever) to integrate functions to camera and to integrate camera into other apps. Along same line: make sure you can *invoke* camera in arbitrary modes, I.E. have a desktop shortcut / shell cmd to start in video mode, and another to start in still pict mode.

It's been discussed ad nauseum to make flashlight switch on immediately on opening cam slider (and popping up a menu with "start photo cam" / "start video cam" / "config this menu, and flashlight brightness" buttons - maybe also dependent on accelerometer and/or ALS)
Paparazzi mode: Start video immediately on opening slider.
