Jon,
It's good to see the swatches being worked on. Shift+click now works, which is excellent. Some comments:
- please remove the padding between the swatches (not only does this waste space, but also makes the colors harder to discern due to a well-known optical illusion)
- please make it remember the display mode and the loaded palette across sesssions (and the window size/placement too, of course)
- please do something with the menu and X buttons, they are rather ugly (why don't you just copy them over from Gimp, they're nice there)
- please fix it to not display the scrollbars when they are not needed
- could you add a "no color" button to the beginning of each palette, which would set "none" to either fill or stroke
- what is eek-preview.cpp? is it temporary? if not could you please rename it to something more useful?
