New screenshot!

There are three new things, two of which are visible.

1. First off, you can see a preview-area upright. This is very useful when editing a sprite close-up, and wanting to see the result immediately instead of the tiresome zoom-in/zoom-out procedure.
2. There is a small left-pointing arrow just above the palette, it's used to hide the palette (or show it again - then pointing right). This is the first graphical widget. Earlier, only rectangles and text widgets have been seen! (yes, they're graphical too, but you catch my meaning)
3. The color slides are working, even if the mouse pointer leaves a slider's rectangle.

That last improvement took some time to engineer, due to the design of the gui-system.

Coming up:

• Toolbar with all-graphical widgets and the now have-to-have show/hide button
  
• ToolTips text line, probably at top line of screen, used as an online help system (but cannot replace current help since it's only displaying messages for widgets, and not all actions of pixelate are due to widget interaction of the user, eg. ESC quits pixelate. Maybe try to add buttons for every action possible..?)
• Color shading as mention below
