I was hoping you would chime in here That would be fantastic! I agree the labels will probably:
1) need changed
2) RR Source would have to be altered to remove the native gas code.
Honestly, the native code should be removed, as it is really just "dead weight" in the RR source now
In the mean time probably just altering the labels to match your plugin can be done for now, and the code in RR can be removed at any time in the future.
Actually......... I just thought about this some more..... I do not think the labels will need changed in the skins.... If the GPSGAS function is not called, and just a load skin is used, it will never trigger the internal RR code to attempt to create the labels. This will leave them "free" to be used by anything. This would save a lot of updates for skins, cuz just about every skin out there uses this feature......
