Defining your default canonical arbitrary is most useful for those unfortunate souls who have their site URLs in punycode. This plugin allows setting a default custom URL to be used as canonical. It is designed to work with Yoast SEO only. The individual settings are still available and can be edited as before. Since it is dependent on presence of Yoast SEO, this plugin will not activate without it. 
The plugin does not add its own settings page, It uses WordPress Settings -> General. Look for it at the bottom of that page.

This plugin disables WordPress’ URL autocorrection guessing feature. 
If you for example enter the URL <code>http://www.myblog.com/proj</code> you won’t be redirected 
to <code>http://www.myblog.com/project-2013</code> anymore.
This plugin is based on the example here: https://core.trac.wordpress.org/ticket/16557

It's not really needed because the code can just be put in functions.php, but this does make it easier for people who don't know anything about PHP.
