I wrote a new HTML Element identification tool for the test automation community which I call Looking Glass. It will auto generate xpath, css selectors and all other ids used by Selenium.
You can verify your own Selenium ids and you can even see if selenium is able to click HTML element without having to run your whole test case.
I wanted to create a tool which is useful for automation engineers that is also compatible across multiple browsers (Chrome, Firefox, IE and Safari) and OS's (Win, Linux and OS X).
Please take a look and let me know of any issues or any features you'd like to see and check out this 4 minute video that gives a quick overview of it.
