Presentation Mode

I would love a "presentation mode" that would allow me to walk people through a workflow during a Zoom call or would allow me to record a video presentation about the same with something like tella.tv.

This is almost possible now, but I would like a full screen option, and I would like the sidebar to be configurable so that notes or other sections can be toggled on an off to keep the presentation clean.

I know we can already do something like it in the preferences for each workspace, but I think an explicit mode for presentation styles would be super useful.
