Fatso is a productivity plugin designed to improve the Gutenberg editor experience in WordPress. It addresses the common issue of the narrow editing space by expanding the width, allowing users to utilize more of the available screen real estate. This enhancement facilitates a more comfortable and efficient workflow, particularly when working with blocks, as it eliminates the constraints of the standard 610-pixel width.

In addition to simply widening the editor, Fatso includes a settings page where users can customize the size of their content within the editor. For an even more optimized experience, it is recommended to use Fatso in conjunction with other plugins such as Welcome to the Block Editor B Gone and Fullscreen Mode B Gone, further enhancing usability and creating a more streamlined editing environment.
