the minor one is with the color palette, some choices are not useful.
e.g. : the cursor bar in the menu only differs slightly from the underground.
The overrides area is nearly unvisible.
Not owning the camera, there is not much I can easily do about this. The value picked for CAM_BITMAP_PALETTE in platform_camera.h might not be the best. But for now, you can change the colors by using the CHDK Visual Settings menu.
The second is hard to explain:
All CHDK stuff is visible on the screen on the right place.
When I press the shoot button half, all areas belonging to CHDK jump about two lines up.
The next halfshoot they jump back downwards.
Do they stay "two lines ups" when you release the shoot half button ? i.e. can you scroll though the menus and do CHDK things and the CHDK stuff stays up until the next half-press ?
While I am writing a third thing:
The free storage field and the bar at the bottom and the raw quantity field are always flickering with random values.
That should be fixable ... I'll take a look tonight. Which firmware are you using - the lib.c code is a bit different between the two version (and it should not be).
