The Daily UserScript: Auto Expand The Google Webmaster Navigation
This userscript will automatically expand the Google Webmaster Tools navigation submenus.
The Unpleasantry:
Currently you either have to memorize all of the submenus and make two clicks to get to where you want to go in Google Webmaster Tools, or you must expand all of the submenus of the navigation manually (3 clicks), and then click the item you want. So it takes 2-4 clicks to get to where you want to go.
The Alleviation:
Once you install the "Google Webmaster Auto Expand The Navigation" UserScript the submenus will automatically be expanded, so it will only take you 1 click to get to where you want to go within the tool.
