Take screenshots of entire websites. Alt+Shift+S is the default shortcut (Option+Shift+S on Mac).
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.
I made this extension after I became tired with the increasing amount of bloat on the extension I was using previously.
Note: Chrome 59 now has a built-in way to take these screenshots with less issues than this extension. https://developers.google.com/web/updates/2017/04/devtools-release-notes#screenshots
Note: Chrome 55 or later is required since v0.0.2. For earlier Chrome versions, you can get the source code of v0.0.1 from GitHub and load it manually.
