Also I find it really devious to create a new set for creating and updating a resource with a new set for each template.
Is there a way to apply a set for all or multiple templates and actions (create/update)?
In terms of the VersionX tabs, there are system settings included in the package where you can enable/disable them. Not sure if the SEO Tab extra has the same, though I guess that one sorta loses it's primary function if you were to disable the tabs
