By activating this plugin autosave feature in the Gutenberg editor will be disabled. Alternatively it also provides options in the editor to select a different autosave interval time than the default 60 seconds.
The block editor will still use local autosave that saves a copy of the edited post to your local storage and allows you to restore it if you happened to navigate away without saving. This plugin prevents the editor from making periodic requests to “*/autosaves” REST endpoint, which disables the “Update” button of the editor, typically at the exact moment you’re trying to click it.

Disable Gutenberg Autosave

Allows to control Gutenberg autosave interval or disable autosave completely.

WordPress is excellent with a great amount of features. 
But in some time, We don’t need all. So I code the plugins to disable the part of them to optimize our blog. 
If you have any question or find any bug, you can visit <a href="http://goto8848.net/projects/super-switch/" title="Super Switch" rel="nofollow ugc">Plugin Homepage</a> to submit it.
