Currently, shared prototypes on the web show navigation controls at the bottom sometimes, but not always. Specifically, nav controls are only visible if (a) the commenting sidebar is open, or (b) all the time, if the prototype has no clickable hotspots (interaction wires).

As the author of the prototype, I'd like to be able to make the nav controls visible all the time -- even if I do have interactions defined.

There may also be use cases where you want the arrows hidden even when a user is leaving comments.
