As a Developer I would like and it would be great to have the ability to select from a list of UI themes, including menus,table grids,etc when creating my App from the newly built in style guide feature (Ver 5.1) or from scratch. This is so I can have a different look and feel for different customers and not just the blue standard theme with basic menu links.
Further it would be great to be able to add new themes from third party providers or create my own.
