How do we hide a canvas?

We have an OmniGraffle 6 document with several canvases.

How do we hide a canvas? The old forums hinted that this may not be possible.

Google shrugs its shoulders at me. Searches on this forum come up dry.

I hope I exhausted my resources, if not please point me to an answer.

If no answer please pointe me to the spot to leave the envelope of money for the dev team. :D

TIA,
Don

I don’t think it is possible. What is your use-case? You can of course, hide all canvases by hiding the side-bar.

Wow I guess I should set up alerts for these threads. :) Apologies for the late response. I need to have multiple canvases on one OmniGraffle Pro document. Instead of having to create separate documents.
