Take screenshots of entire websites. Alt+Shift+S is the default shortcut (Option+Shift+S on Mac).

NOTE: I am not going to update this to MV3 so it will probably stop working in January 2023.
Note: In Chrome 59, a built-in feature was released that can take full page screenshots. It works better than this extension, so I recommend that you try to use the built-in feature instead of this extension. Please learn how to use the built-in feature here: https://github.com/stefansundin/one-click-screenshot/discussions/15
This extension is very simple. With just a few clicks, you can take a screenshot of an entire website and save it to a png file. There is no bloat or any fancy post-processing. There's also a keyboard shortcut that you can use.
