Opacity supports "Export to Canvas"
Looks like I may be able to soon replace Adobe Fireworks as my image editing tool of choice for the web. Ajaxian recently featured a new tool called Opacity, and if you follow through to their website, you’ll find a great video tutorial that shows how you can create great looking icons and simple images.
Another feature I also love is the integration with the various OSX FTP clients like CyberDuck and Transmit, as well as the dynamic web preview option.
With <canvas> being relatively new on the scene, a tool like this could really bridge the gap between designers & developers and accelerate the adoption of another open standard that can help push the “open web” forward.
