It's not a problem, I quite enjoyed the challenge but it is a lot harder than I'd initially anticipated.
The last real iOS hitch is implementing my fake scrolling idea across all elements which require scrolling in Adapt. I'll have to build a little library to do this, but it is possible (in theory) to reimplement scrolling inside iframes using css 3d translation effects and a couple of touchstart/touchmove event handlers to capture the movement.
Testing, help and advice are always appreciated :D thanks for the friendly nudges!
Oh, the index.html file in the extension is really simple iframe for testing the fixes. Just build adapt and run it through that file or your own iframe file.
