It would be nice to be able to have the option to use Split Screen as this shows https://support.smarttech.com/docs/software/iq/en/getting-started/split-screen.cshtml . Some of our boards have the V3 and teachers are able to use it while other teachers have the V2 and unable to use it. All of our teachers want to use it. Can there be an update to the software to allow this for previous MX versions?
