Hi there,
the software is really awesome. I like it a lot, but i discovered one small problem (totally a luxury problem).
When i load a model and add support structures (automatic or manually) these structures stay there, even if the model is reloaded when simplify3d discovers that the model has changed. When the user decides to let the model reload and print it right away the support structures may not fit the model he reloaded from disc.
I think it would be better to remove the support structures when a change is detected and the user decides to let the model reload. Maybe it is also good, if the view is resetted to model mode when currently being in preview mode, since the preview doesn't represent the loaded model when it was reloaded.
