I’m a Noob, so I’m sorry if this sounds impractical … 
I wanted to request a feature for executing a custom JavaScript code inside an HTML5 game from the Events.
What for? Well, my logic is that if such a feature is available, users can use custom JS codes for eg. to log in Facebook, publish/share the Game progress in game as Facebook status. 
If it’s not practical, a support for using Facebook API through Events would be great. What do you think about it?
PS: While I’m writing this, I’d like to mention that i’ve Not used the Facebook API.
