In the most recent update of Safari (Safari 3.1), we now have the option to show a “Developer” menu (without any hacks) when using the browser.
There are all kinds of goodies in the “Developer menu – one which I will end up using quite a bit: Web Inspector which is helpful for a number of things (viewing code for errors, optimization, even CSS editing if you want in the snippet editor).
There are other nice options as well such as a quick and easy way to “Disable Cache”, Disable Images, etc. If you do any web development and are a Mac user – make sure you check this out.
Great work on the update!
