I'd love to see an update for the brush tool at some point to make the tool more versatile. Could include: different brush tips. Additional brushes in various shapes and styles like charcoal, acrylic/grunge, dots or calligraphy brush tips Advanced options for the brush tool. Along with the options of size, opacity and softness there could be options for rotation, transformation, area painting and options to manipulate the beginning and ending of a brush stroke (ie fading edges, smaller edges, bigger edges...) (- Improvement for users with a graphics tablet: Pen pressure support)
