# prominentTabIdentifier

The identifier of the tab that should be displayed as prominent. Where supported, the specified tab receives enhanced visual emphasis in the tab bar. If this property is nil, and there is a UISearchTab that could become prominent (when automaticallyActivatesSearch = true), then the search tab will receive the prominent treatment by default.
