Some initial thoughts during and after build...
- Make button holes larger - buttons get stuck down, and separate them a little more as they are too close together
- Add a spacer (or another set of redundant headers) to the top back of the screen to make it level
- Buttons are very loud when pushed, perhaps change for less noisy ones?
- SD card slot doesn't have the spring inside like others I have used, meaning it is very hard to remove the card. Took a few attempt to get it right because at first switch on it couldn't read the card
