Submit a new story to Pivotaltracker
A handy extension that enables you to submit new bugs right from your browser.
You can also attach a screenshot of the current website to the story. This is especially useful for reporting bugs. The extensions also allows you to annotate and draw on the screenshot before submitting.
There is a similar extension called "Pivotate" but it stopped working and I could not fix it. That is why I made this rewrite with a slightly different style.
