I have created this plugin for personal use and have decided to share it here for everyone else.
Since the release of 4.20, the bulk edit products feature was removed. This plugin was created to bring back that support.
I have included the source code of this project to allow anyone else to extend off it as I created this for my personal use.
This will create a sub menu item under "Catalog" called "Bulk Edit Products"
Hope this can be useful for anyone else missing this functionality :)
