Hi, if you are a developer, you can use the Page customization object to modify roles.
It is similar to Page Extension in terms of modifying the layout of the page.
You can modify a role as follows, from within the Profiles (Roles) select Customise pages
This will open a new window where you will then be able to customise as normal.
With regards to security you will still need permissions to make sure that the users cannot navigate to other information so using both permissions and customisation should limit user access.
