Currently even for paid subscribers it is only possible to run one instance of the app (not counting the mobile app, where I can still be connected). Why not instead allow also one read-only instance on the same license?
It would be like providing the mobile app on Windows too, only better doe to the ability to run a simulation.
I would set that up on PC/tablet next to the machine and refer to it whenever I'm trying to remember what was I thinking about doing in the next step without interfering with my programming machine and the designs I have in progress there.
It can also be used on a 2nd display to help those learning Fusion by providing easy access to a reference/example design, without having to constantly switch between docs that hide one another.
