Yes. Allowing the use of Breakdance's lightbox on non-BD-created content like posts would be very practical. It's doable, as Supa Mike demonstrated in the Facebook group, but it would be great to have as a built-in option because it makes much more sense than using another plugin for non-BD-content lightboxes. WP has its default lightbox now, but even then there are two different lightboxes on a site and there should be no need for that.
