There is ability to use Box.net via two locations - which (once you have logged into box initially) prevents you from having to open another window or tab and re-login there - while working within the Advologix application/Salesforce platform:
- on the matter page; via the Box.Net section
- the Box.net tab
within the Advologix application; and view documents / document folders there.
Box.Net Window on Matter Page
A window into Box.Net can be added to your matter page.

Box.Net Tab

The Box.Net tab allows you to enter Box.Net without exiting Advologix. From the Box.Net TAB you can utilize the application just as if you logged into it outside of the Advologix application.
