There are a lot of very smart people on StackOverflow and most of them are smarter then me. I think even if you're not going to respond to any questions it's worth just reading other developers' questions and answers.
I made this extension about a year ago but I wasn't able to finish some important features and bug fixes until now. Shame on me!
Right now it supports only StackOverflow but I want to include all Stack Exchange sites.
You can install it from Chrome Web Store.
