OmniSketch version 1.5 has been approved and should be available on iTunes soon. This version was intended to contain an additional set of 24 brushes that you can purchase for 99 cents. Unfortunately I missed a step in submitting the App and the actual In App Purchase isn’t available yet. I’ve already submitted version 1.5.1 that will have the brush set available for purchase.
1.5 does have new, hopefully more intuitive, icons. It also gives you the ability to copy a picture in the gallery.
1.5 only took a couple days to get through Apple’s review process. Hopefully 1.5.1 will get through as quickly.
