Being lazy here:
@Zilver: Yes it's missing. I'm not entirely satisfied with how initialConfigFunction currently is used, and I'm mainly focusing on separately spawned sub-frames, which currently do that through the XML template as shown earlier.

@zork:
"Time will tell. 4.0.1 is coming this week. Which version of oUF is gonna work there?"
1.5.x
and
No, that's the wrong use of initialConfigFunction. Use oUF-initialConfigFunction as tukz does. See below.

@tukz: toggleForVehicle is going to be set on "all" frames with 1.5.x. I mentioned it somewhere else that I'm killing disallowVehicle switch.

You can use oUF-initialConfigFunction like you do, but please keep a track on the changes made to oUFs git before posting code.
