I've been working on a browser extension called More Rich Results that you might find useful. It just looks for Reddit and Stack Exchange results and previews them in the sidebar. It makes for a pretty clean search experience when developing or looking for opinions.

It looks like this: https://i.imgur.com/kb5OE0n.gif

It has definitely improved my workflow and a lot more features are planned such as Github repo/issue previews and support for Searx. It currently works with Google and DuckDuckGo, although it is still in the early stages.

To install you need to download the repo, enable developer mode for extensions in your browser and press Load unpacked.
