Description
block-region classes are a necessary requirement in layout files for themes to be able to work correctly when using AJAX drag-n-drop. At the moment CANVAS is missing these from region-post and region-pre in canvas/layout files.
Also, like BASE theme, CANVAS should have the custommenu php in the layout files too, so that if CANVAS is copied to use as a base for new themes all the php is included that needs to be.
