Create extension Add-in
I have added a new Add-in for TRUDUtilsD365 - "Create extension".
It allows you to create an extension for the current element(or add it to the current project if the extension already exists) from a designer view.
In the standard tools, you can do the same only from the Application Explorer and in some cases, it is not very handy.
Download the new release using the following link and try it. https://github.com/TrudAX/TRUDUtilsD365#using-power-shell
