We are just a couple of weeks from having GA by the way and some of the things we are adding are just amazing. Take a look for instance at this transform.
http://www.emitrom-lienzo.appspot.com/#ExplorerPlaceImpl:transform_3_points For the user of our API ... one line of code for that complicated transform. Behind the scenes ... a lot of stuff going on. - All shapes are grouped. - All shapes are draggable. The level of sophistication you'll find it's simply amazing and we are just finishing off 1.0 GA. The package is very light and has no dependencies.
