See @jfg 's answer above: https://community.troikatronix.com/topic/8402/answered-audio-and-movie-players-elapsed-or-remaining-time/8The zoom controls at the bottom right of the Scene Editor/Control Panel let you zoom the Scene Editor or Control Panel in or out, so you could zoom in to make it bigger. The keyboard shortcut is "Cmd and +" to zoom in on macOS and "Ctrl and +" to zoom in on Windows. The zoom options also exist at the bottom of the "View" menu.
You can also change the default font size of Actors and Controls to make all that text bigger if you go to Isadora > Preferences > General tab (the first one) > User Interface > Actor/Control Font Size
@whatnao You could also run the projector in an activated scene with a keyboard watcher that listens for a trigger and toggles the projector on or off - so the movie keeps running and the projector is what goes on or off. Since the scene is active the keyboard watcher will react even if you are currently in another scene.
