Hey, I wanted to ask this: (I must admit this is a very subjective suggestion)
While I feel most of the stencyl interface is pretty well organised, the way drawing blocks works (even before this extra API was introduced) seems a bit needlessly complex. I understand that the newly released image API is a recent change and that there is more pressing stuff right now, but do you plan to make the drawing user interface in stencyl a bit simpler/more intuitive at some point in the future?
Personally I'd feel it would be best for image types (not instances) to be created from the dashboard like with object types instead of in code. I think blocks like "blank image with width..." and "instance of (image)" should be added the prefix "new" to be clearer and prevent the kind of mistake your stencylpedia page on the image API warns against. Also, now that there is the image api, the old tab for drawing blocks seem redundant(except for compatibility reasons). Having 2 separate tabs to do a similar job can be confusing.
Also, while I have no experience using these things, the new hardware-accelerated shaders seems pretty rad
