[QUOTE=SketchyLogic] For anyone wondering about the effects of screencanvas rendering in the latest update: I've noticed an all-round boost in frame rate on iOS via CocoonJS. In my game, there's a significant increase during cut scenes (essentially 3-5 large sprites being panned slowly) - the scenes have gone from ~30FPS to ~42FPS. However, the increase is negligible during gameplay (10-15 sprites, basic physics, GUI overlay) - the scene has gone from ~28FPS to ~30FPS.
This means that the change probably won't make a previously unplayable game playable, but it might help make for a smoother experience.[/QUOTE]
Screencanvas improves rendering speed for sure but it depends on many things: The device graphics hardware and driver, the application rendering pipeline, etc.
About keyboard support, CocoonJS provides a text input dialog for basic text input (checkout our extension file CocoonJS_App.js for the TextDialog related functions and also our TextInput demo at http://storage.cocoonjsservice.ludei.com/demos/cjs3801793643225403841keyboard.zip). I guess you are talking about external keyboard/device support. Adding such a feature is not in our short term roadmap unfortunately.
