We've given the popups the ability to trigger JS events and we will be adding the ability to trigger popups with JS events as well.

Could you send me an email ([email protected])? I'd be more than happy to send you an invite immediately if we could work together on making this work for you, single page apps are definitely something we want to be viable for.

Edit: Bunker looks really cool. If I start freelancing again, I might just have to try it out. ;)
