The configuration of Asset Publisher contains many different options and they are all under the same tab "Settings" tab.

In order to make the configuration easier to use and to understand, we should create a second level of tabs and divide them. We should divide the current configuration in the following tabs:

1. Asset Selection -> Will contain "Source", "Filter", "Custom User Attributes", "Ordering and Grouping"
2. Display settings -> Will contain "Display Settings"
3. Subscriptions -> Will contain "RSS".
