Handing changes to available values of settings
With my Canon DSLR, swapping lenses or zooming (for instance) changes the possible values for "Aperture". But the settings shown in Entangle don't change.
This can be fixed by disconnecting and connecting. But should there be a "refresh" button instead? (Ideally this wouldn't even need to be done manually, but gphoto2 and perhaps the camera itself may not provide a way to avoid it other than repeated polling.)
