Extract palette from canvas feature for color menu
It would make palette creation/color changing easier for people (like me) who like to focus on the pixel art first then focus on the colors and palette later.
This can already be done manually by exporting the image of the project somewhere then going to the menu - "Color>Import from image...", find and select that exported image, then you have the image's colors in the palette section.
It would go in the color menu and be called something like "Extract palette from canvas" that automatically exports a .png file to some temporary place then automatically imports the colors from that image just like the "Color>Import from image..." feature. Implementing this feature would a nice time-saver.
