,,,that has 4 functions in order of importance.
1...COLOR: a set palette with an ability to make the palette darker, and an opacity function. i believe "drawcast" has both.
2...TOOL: a shape tool (with at least a rectangle shapemaker) that has color fill. this tool is hard to find.
3...a save/send as jpg
also,,,as little lag time as possible. i hate sketchbook. drawcast is okay.
thx all. too many art apps. they should have a subcategory
