Hi Stephen! Thanks for the note here, and for your patience in waiting as we work through the queue to get you a reply. We do have a number of users running our plugin who are also using WooThemes’ Canvas — in fact we’ve been working with Woo on a handful of plugin/theme conflicts recently and have taken a few steps with them to specifically/officially integrate the two codebases. It looks like specifically in our 3.1 release we added code to better integrate the two.
That said, I have seen reports of users facing conflicts since then. While it looks like in most cases they were able to work through their issues with our support staff, I will caution that it does seem our plugin won’t integrate 100% “out of the box” with Canvas at this time.
Hope that helps and sorry I couldn’t offer more. If you have other questions do let us know!
