A site is preparing to roll out Vault 2014 with the usage of the Thin Client, however this site current does not use Item Masters. Their Question which became a great idea was:
The possibility to “deactivate” (hide on a global level) the “Item Master” buttons in the Thin Client regardless of what permissions are given to the user; which could then be “activated” at a later date when Item Masters are used.
This would could help for sites that do not use this option in vault and would reduce the questions from end users on why how and what.
