If you’re a Mac user and haven’t tried FluidApp, I would highly recommend you do. In short, it creates applications out of websites using webkit (I think) and it works great for Google Wave and Google Mail – even with a ‘new!’ badge that shows up on the dock icon showing how many new messages you have.

I made a Google Mail icon for it (above), in case you’re having trouble finding one. Feel free to use it, copy it, change it, share it, etc… and say thanks in the comments so I know you’re enjoying it!
