Some suggestions for future updates...
1) Currently you can add lights, but cannot delete them afterwards. Need the ability to delete added lights
2) Creating, Edit and Saving of project settings so we can comeback and edit what we have made. From programmers viewpoint... you would just save a text file of the path to the image and all the settings.
3) If you keep the export canvas function, a) change icon to something else beside an animation/video icon; b) The ability to edit the dimension (WxH) of the canvas.
