Describe your feature request

For models that have a large number of inlines, the present options are to put them on the general tab or to give each of them their own tab.

I would like to be able to group several inlines in a single tab.

For example, I have a primary model for "Customer". I have a related model for communications preferences, another for phone call logs, another for email correspondence logs. I would like to have a "Communication" tab in which I have the inlines for all three models in a single related tab.

This could be accomplished by giving the base model inline class a tab_group attribute and perhaps a tab_group_order attribute.
