In v2.2 there is a new UI. It is installed as the default UI (default URL) when you install the administrative UI
General information
This UI is based on ajax. The URLs change for bookmarking and back button, but the page does not reload (so the tree can remain in a constant state)
Main screen
The main screen is a dashboard that shows a search, quick links, a tree control to browse the repository, recent tasks that the user has performed, and small windows that the user can use to find what they need in Grouper 
Linking
The new UI is linked to the old UI and lite UI and vise versa.
Search
There is a search box at the top right of the main 2.2 UI screen where you can search for entities, groups, folders, attribute definitions, or attribute names
Tree browser
The tree on the left shows folder, groups, attribute definitions and attribute names. If you click on an item in the tree it will go to the main screen for that item. The folder is ajax based, it will retrieve the data as you click on items. It will only show a certain configurable number of items in a folder so there are not performance problems. The tree is secure, only items the user can see will be displayed. As edits to the registry occur, or as screens are navigated, the tree on the left will not change (so the user does not have to re-navigate). To repopulate the tree, click reload in the browser.
