The following is a brief summary of the customization features available beyond the standard sections and field order. These allow you to add graphs and custom UIs that help combine the layout customization with the flexibility and power of Visualforce:

• Visualforce: Layout sections allow you to embed a Visualforce page using Standard Controllers. While this is only supported on standard view pages, you are able to do whatever you wish on the Visualforce page itself.
• Report charts: Recently, the ability to embed a report chart into a layout has been added to the platform. This is a powerful feature to enhance the information provided to the user using a parameterized report.
• Actions: These allow you to describe, either declaratively or programmatically, additional actions beyond the standard platform actions. They are only applicable if you have enabled Chatter for the object.
• Custom buttons: Much like actions, these allow additional buttons on the detail and list view pages to invoke application-specific functionality. Creating Custom Buttons and hooking them up to your Apex code is covered in Chapter 8, Building User Interfaces.
