I was wondering why SMART decided to implement desmos into Lumio instead of GeoGebra (as it already is a part of then SMART Notebook® software). In the German speaking regions like Germany itself, Switzerland, or Austria GeoGebra is the standard tool for math teachers in the classroom. So please make the GeoGebra widget an option in Lumio as well in order to provide a consistent experience in SMART Notebook® and Lumio.
