Ah yes move with the middle button is a good idea. It's done on SVN.
I don't want to remove the buttons in the color window, but I take a note of making a bigger preview of the color.
More suggestions :
- keep content of layers after they are moved
- read/write more formats (LRS, RES, RAW, TIM, BMP 16 bit iGo)
- focus on child folder when going in parent folder in browser
- use fphttpclient and thread to get online files
- layer effects (stroke, shadow) and layer groups
- layer mask
- text layer
- add dark skin option for toolbars
