I was asked to post this question here so it could be answered publically, so here's my question
The canvas has a vertical ruler/guide showing the page (height) limit with a yellow line. Is it possible to get a horizontal ruler with page (width) limit line as well?
I often have images that overlap both limits and have to keep shifiting the image to see if I'm still within bounds.

Hi Bianca,
Thanks for posting it here!  Hopefully it will help someone else in the future.  Here's how you can create your own guidelines by adding shapes to the Master (as well as a few other notes about managing large images) - https://www.screencast.com/t/qGpPNWf3n

Hope that helps!

Thanks! I'll try this out next time.
