What's the difference between Sketchbook Pro (Windows) and Sketchbook for Windows 10?
Sketchbook for Windows 10 runs on any Windows 10 tablet or PC and is optimized for touch. It works with the Surface Dial, has unlimited undo/redo, and supports HD display and 100MP canvas size. Though this version currently excludes the following features, we’re continually adding more: transparent color, layer grouping, French curve, text tool, FlipBook, crop tool, image adjustments, and distort.
Sketchbook Pro for desktop (Windows) only runs on Win64 devices and contains the full feature set.
