Visualforce Homepage Component Type
You should be able to add a visualforce page as a component of your homepage. Similar in nature to the current ability to add a visualforce page to a page layout. The current workaround I've been trying is to include the page in an iframe, which works but not as swiftly (in terms of loading especially). The concept would be to create a page with headers and sidebars off and display any combination of lists, details, custom components... and have it show up as part of the homepage.
