For spare parts type websites why cant the interactive svg be interactive in the preview? It is interactive on mouseover (of sorts) in the design and prototype modes but not in the preview where it is actually needed? First attachment is the design/prototype view (highlight on mouseover) and the second is preview.....no highlight on mouseover

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.

When sharing a design with multiple sizes and a black background it becomes impossible to see the edges of the screen. Adding a 1px #555 line would be enough to improve the preview experience by allowing the user to see the edges of say a small mobile screen on fullscreen.

Please remove this annoying overlay (please see the screenshot). It covers the art board and influences first impression.

If this is needed, please add it to loading screen before loading the prototype. Something like Invisionapp has for example.

Drag any object from the canvas to create a thumbnail image for web preview. See GIF
