Tab Switcher is a powerful browser manager for Safari and Chrome that provides fast switching between tabs and windows. This app will list your tabs and you can switch or bring them in front instantly. You can also filter, navigate around and apply commands with your keyboard.

It's a sandboxed, extendable live-testing chrome extension and framework! It runs pre-defined and custom tests on each page that you visit - collects the whole lifecycle of the pageload (HTTP headers, server response, onload DOM, DOM after complete JS execution,..) and delivers direct visual feedback.
