Nice camera app, but start up time is a little slow.

One thing I miss in about any camera application is the option to save your own presets.
My DSLR has this option and lets me quickly recall settings by selecting C1, C2 or C3 on my dial.

It would be nice if we could save some (3 for example) custom settings and these settings could then be quickly accessed by pressing a numbered or colored button on the left of the screen.

How could this be implemented?
- User sets the camera settings
- User presses one of the preset buttons for 2 seconds to save the settings
- then the user can press a preset button to quickly recall the settings behind that button.

one could then save for example the following presets:
- normal mode with flash
- normal mode without flash
- night mode
