Mac OS X Interface
Much interface design at Omni has started with a quick mockup in OmniGraffle. Here's the stencil I've been building, adding elements as I need them. Most designs start with an existing screenshot, with swatches of controlColor over things we need to get rid of, and layers of new controls on top of that. Clearly there are lots of controls that could still be added to this stencil. If you create any, hop on the Omni forums and post your own version! Together we can create the ideal Mac OS X interface stencil. Update: Check out the updated version of this stencil.
