This plugin allows you to do the following: 1. Change the order that your plugins are loaded. 2. Selectively disable plugins by any post type or wordpress managed URL. 3. Adds grouping to the plugin admin age.
BB will only load CSS on the post types that you have enabled and only if using BB on those post types if that makes sense. You mention a conflict in the above, are you experiencing an issue with BB and Shortcodes Ultimate?
I deleted the staging site with the original conflict (@ several weeks ago). I just re-copied the production site to staging. Added Beaver Builder to the staging site home page - and no conflict on the course/lesson custom post types with Shortcodes Ultimate!
