I created Categories for SEPTIM Zackalope's load order and Installation guide.  For use with the latest version of Nexus Mod Manager.

Installation:
Go to your NMM SkyrimSE\Mods\categories (ie C:\Program Files (x86)\Nexus Mod Manager\SkyrimSE\Mods\categories)
Make a back up copy of "categories.xml"
Extract this file into the folder.

Thanks to:
zackalope for the Excellent Guide.
