With extensions for Safari 5 finally being enabled, developers are starting to produce some good stuff.
One thing (which Apple has never had) is a separate reload button. I dislike buttons which have two functions such as reload/stop. If you click ‘stop’ just as its loaded, and changes it’s state to ‘reload’, thus loading it again. Grrr annoying. Happens too many times.
