* Follow path (drawing a path for sprites to follow as in Clickteam Fusion)
* More animations in Sine behavior and more animation controls.
* "move to" plugin (should be included within the official C2 releases)
* Transitions between layouts
* Advanced camera with easing (ease in \ out)
* iframe (should be included within the official C2 releases)
* Squash and stretch for Platform behavior to achieve cartoon like movements without using animation frames
* Share for android games (opens native android dialog with all installed social apps for share and this is only available with CocoonJS)
Very nice Suggestion!!
Very Extremely usefull features :
Moving object with ease control. Say you want your object move from point A to B with ease control.
Built-in transitions between layouts. This is so crucial, how can construct 2 doesn't have transition between layouts
