Wanting to save some space in Gmail, or perhaps you’re just tired of the text-based main links to browse around your e-mail account?
The GMail Compactor user script will help you reclaim that space with style.
As you can see, from the picture above, after you install this Greasemonkey user script, everything from your Compose Mail link down to your Contacts link are now minimized into very pretty icons. As an extra benefit, you also still get the count of how many new messages are in some of your folders, such as Spam. If you want to maximize the vertical real estate in Gmail, then pick up the Gmail Compactor user script. (found via Lifehacker)
