Thanks for bringing this up, we are thinking about possible solutions because during play mode we need the mouse interaction to go directly to the controls in the stage, mouse can't be used to zoom in/out or pan the stage contents.

We'll come back with some ideas to discuss.

Yes, I think what we could potentially do here is to essentially conserve the aspect (zoom level and position) of the Stage within the viewport when Play is pressed.

So for example, if you happen to be at 400% zoom, with the UI panned off-centre to the left, it would render exactly as seen on the Stage prior to pressing 'Play'. And if a user wanted to see their screen exactly as it renders now (uniformly filling the viewport), then they can simply press the 'Fit All' button in the View Toolbar prior to hitting 'Play.

There might be some challenges around still granting the freedom to Pan/Zoom during Play since technically the keyboard and mouse interactions are reserved for the Page being played, but this approach would grant the flexibility to achieve what you're looking to do!
