Congratulations on having it be usable on an iOS machine straight out of the gate. This is something that still eludes scaladoc, for example.
It does render, but it seems like the search engine initialization is blocking for quite a while on iPhones, and in portrait mode it could use some more responsiveness.
Did you try it on an iPad or what device exactly?
Anyway, thank you for your work here. If you ever want me to be your iOS guinea pig (phone or tablet) let me know.
