trigger.io：标头的Web视图？

Question

Using trigger.io, is there a way of specifying a web view for the header area?

I currently have a rather complex header that utilises media queries and includes an input box depending on the current screen width. This extends far beyond what the trigger.io's native topbar implementation is capable of so I was wondering if this is possible or is potentially planned?

At the moment I'm utilizing position fixed for devices that are known to support it, but it would be nice to have full support on all devices (mainly Android 2.3>*).
