#About

This userscript/extension replaces the review button with a dropdown that lists all the review queues on the current site and the number of available posts to review. It simply saves the trouble of going to /review and coming back if there's nothing to review. It also adds a quick access to /tools (provided you have 10k). I know it works in Opera and Chrome, but I was told it works fine in Firefox as well (no guarantees).

#Installation

Chrome Web Store

You can also use this userscript (code below as well) in greasemonkey/tampermonkey or download the Chrome/Opera extension (drag & drop it to extensions, uses pretty much the same code as userscript).
