I just upgraded to the new version of Sketchbook Pro and have been checking out the new features. Biggest shift so far is the addition of a copic marker palette; older version had a single chisel-tip brush, this one has 4 brush tips, a copic blender, and full numbered range of colors.
I've never had the $$ to put towards copics, so this is a new learning curve for me. Thus far I dig it.
