I've been noticing lately that there isn't great support, mostly in terms of the Options, for companies where the same users work in Metric and English. These users don't want to run mapkeys each time they switch between working in Metric and working in English. Furthermore, even if they are willing, they would likely forget and then mess up on the models they are currently working on.
The below two options just became an issue for us this past week. I'm sure there are many more that I'll add over time. The main request is for PTC to come up with a newer option structure that can help support these options either at the model/format level OR be robust enough in the config.pro/sup
