Interesting app. Not sure who the target user is on this. Sketchers?
As far as I can tell, Inkpad is still the cleanest, fastest and nicest Illustration/Drawing app. Full vector drawing, efficient toolset, minimalist ui, .SVG and .PNG outputs. Perfect.
I wish Autodesk would devote resources into fixing & cleaning up their existing neglected apps, the disasterous Inventor Viewer and unecessarily limited Acad WS.
