1. Mac please!
2. Custom palettes. I currently use Studio Artist and you can import a custom color palette to use to "paint" a photo, so even though the picture may have blues and greens, you can choose a custom color palette of say, red and orange, and the program will extrapolate and use the custom color palette of your choosing.
3. Auto paint feature.
4. Text/type tools.
5. Triangle/shape brushes in coordination with auto trace.
6. Layers and transparent background like photoshop.
Looking forward to the new release!
