I noticed that too but then I kind of felt like that's the point. Simple. Kind of like having a box of 9 crayons instead of a box if 200.

The more options they give you the more time spent use them instead of drawing?

At the same time though, I do wonder if the sketchbook UI is really the main point. Going through images 1 at a time or with a grid of thumbnails in Art Rage or Sketchbook is much more cumbersome than this one pinch to fold, flip to next page, tap, draw.

It doesn't ask you to load or save, it just acts like paper which is quicker.

I wonder of those other apps added that type of feature if the limited options would still be a positive or a negative.
