Pekele had a post on the GP32 Xtreme Webboard about the latest progress on his GP32 drawing program. Here is a copy and paste from Pekele’s posting:

now you can trace: -3 lines of various sizes.- a rectangle fills or empty – a circle fills or empty the pot of painting works, I attached it so that it fills of surfaces limited by a black color. the eraser and the eyedropper function work. The interface of the tool box was improved with a color of selection while moving cursor.
