I'd like to have a tab in the ribbon for multiple file management in order to have the ability to update scope boxes, referenced views (sections, elevations, callouts,...), title blocks, revisions, keynotes table path, shared parameters path, materials library, object styles, line patterns, view templates, legends, family definitions (either annotations, system or loadable)... consistently across all the project files (usually > 5 files because of the project scale and number of users). Being also able to create a sheet list without having fake sheets because they are created in other files, etc.
