If you are sharing SMART Notebook® files to your SMART account using the menu "Files | Share..." there should be a warning if the SMART Notebook® file is containing objects which won't work in Lumio™ by SMART or SMART iQ™ (like a widget, a GeoGebra object etc.). This would prevent false expectations when opening the files in the classroom with Lumio or SMART iQ™. Of course the perfect solution would be to make all the possible objects in the SMART Notebook® software supported in Lumio and SMART iQ™.
