Go back with back space again
**Obsolete now that Google has published an official extension, switch to https://goo.gl/L30YZ7**
With this extension, use the backspace key to navigate back again (basically, a fix for https://crbug.com/608016). In addition, implements Shift-Backspace to navigate forward since v0.25.
IMPORTANT NOTES:
1. You need to reload your open tabs after installing the extension.
2. Due to Chrome limitations, this does not work on chrome:// pages such as the new tab page or settings [1], nor in the web store itself [2].
