Hey Bubblers!,
I’m in a particularly spritely mood this morning, must be the weather…
Wanted to outline a new plugin I’ve put together recently, it’s called iFrame Popup and has been created purely to get over the limitation when you have a portion of your site running within some embeddable code in an iframe (perhaps you give this to customers), and you want a popup to actually appear outside of that iframe, loading another URL inside the popup whilst being able to pass dynamic data still.
I’ve completed a few jobs over the years setting this type of thing up, so figured it was about I made a plugin out of it. 
Anyway… here’s the link to the demo pages, not too much to digest. All the instructions are on there and inside the plugin doc fields.
I’ll add the link to the plugin page once approved, hopefully it can be of some use. Any changes, additions, bugs etc, just let me know.
