As simple as the topic name implies. Add a feature that would refresh the model files that are currently loaded. This seems like it would be an easy, almost trivial, thing to implement and it would save users time particularly if they iterate designs.
Have done so now. FIrst link was my own from some time ago that had not gotten much response. Searched for, but did not find, the second thread. Seems like such a good feature to add for a trivial amount of effort.
