Fast Page Switch adds a metabox with a drop down menu to the Page editing screen that allows you to quickly switch to a different page. This eliminates the need to visit the All Pages screen and search for the next page you want to edit.
Fast Page Switch saves time if you have less than 20 pages. If you have more than 20, it could be cumbersome to use and outweigh the time saving benefits.
I tested Fast Page Switch on WordPress 4.2.2 and didn’t experience any issues. You can download it for free from the WordPress plugin directory.
