Users gain access to various Arellia Consoles and areas within the consoles according to the access you assign them. So users assigned to different roles with different levels of access within the Arellia Consoles will see only those tabs, folders, files, items, and operations to which they have been assigned access.
When you make changes to roles and access rights, then you change the tabs, folders, files, items, and operations that users will see in Arellia Consoles.
