Thanks to some tips and feedback from the folks at xda-developers, I've been able to make some handy changes to the Screenshot application:
- Screenshots are now captured much faster; images are being decoded directly from the R5G6B5 format.
- Screenshots are now automatically saved to the SD card.
- You can now use the camera button to capture screenshots. (The Screenshot application must be started first)
- If you assign a hotkey to the Screenshot application, you can use that hotkey to also instantly take a screenshot. (The Screenshot application must be started first)
