LabVIEW WPI library suggestions

[apalrd]

A few things I would like:
I have already written a gyro calibration VI (modified WPI Gyro Open VI) and included it in the zip attached. If you set the Center input to 0, it will autodetect the center and feed it to the Center output. If you set Center to a number, it will use that as the centerpoint. It also has the gain pulled out so you don't need another VI (WPI Gyro Set Gain) to set the gain.

Battery voltage - I found it only one level down in WPI Start Communication, but it is never given to teams in an easy way. I wrote a simple data cache in my attached zip, but there are other ways to implement this.

Relay set only one coil - I know how to set the coils separately using the four states of the enum, but sometimes it is nice to set one coil in a totally different place in code (for example, forward in minibot.vi and reverse in lights.vi), and there is no good way to do this. I propose a SetForward and SetReverse VI which sets each coil separately.

I don't know if this counts as a library thing, but I've always felt that the motor function palette was organized upside down. The generic motor VIs are too many levels down in the hierarchy.

Lots of people ask how to toggle on a button press or to do things once when the button is first pressed. It's not hard to create code to do that, but it might help to have pre-packaged functions for teams to use.

The refnum registry is a great concept but it seems not quite polished. It creates a context in the code where exact spelling matters. I'd like to see a provided facility that can do the same thing just as easily but with multiple-choice selections instead of unconstrained string constants.
