@ZdrytchX, CSP often used for Manga artist and Illustrator to doing something. Because the feature specifically either manga making and 2D illustration.
and I know from my friend in japan, Some major manga publisher using CSP for editing manga. So I learning it since my PS corrupt.
CSP bit more complex than Paint tool SAI for illustrating, but easier than photoshop CS for editing.
Only Take 200 K to 1,5 GB Working Set on RAM (depends on your Resolution image) Meanwhile Photoshop CC thrice on that amount, My RAM is cried.
