I would love to see the "prealign" Parameter working in HTML5 (FINALLY!...).

I've added a Tilt sensor to my robotic panorama head and my custom software writes the pitch and roll values from the start position to the <image...> attribute of the xml file.
So i don't need to level my Panohead (sometimes it's just not possible to do it...), but the panorama is always leveled because of the right prealign correction.

It's not possible for me to use the html5 Viewer for this purpose so this is a killer feature to have...

Thanks!

P.S.: maybe there exists a workaround? Let me know...
