Lack of documentation regarding custom transitions

Hi, ever since 1.4 I have been having serious trouble building a custom transition. There is no documentation on custom transitions, I've combed through pagecontainer widget/page change events documentation but I've not found a way to non intrusively defer the transition mechanism while executing your own code in between. I've gotten by hacking away at the jQuery mobile source Javasript and CSS, but obviously that's a less than ideal solution. I would greatly appreciate some advice on the matter.

It seems that no one knows and that this knowledge has to be build. So, can we delete this issue from the current milestone?
