Jensen Harris breaks out information on the new “gallery filters” featured in Office 2007 (more information on the new gallery control can be found here). His example is the new, much more robust Equation tool. It’s a very cool way to handle groups of related items.
The gallery is a major component of the new Office 2007 UI. I love the graphical, touchy-feely, WYSIWYG approach for many tasks, and I love the fact it’s so “live.” It is a major shift from the current UI, and, like the task pane, will definitely require an adjustment to the way we work with Office and train end-users.
