Just thought of another one:
Some way to display more information about the house on screensavers. so when I’m walking by one, I can quickly glance and get an overview of what’s going on in the house. EG - if an exterior door or window is open, lights on around the house on, AV zones on, etc.
Maybe more broadly - the ability for developers to build screensavers for the OSD / T3 / T4 interfaces.
