My setup is as follow:
[*]Blender[/*]
[*]AddonsAssets[/*][*]Blender 2.8x[/*][*]Blender Linux 2.8x[/*][*]Scripts[/*]
[*]addons[/*][*]modules[/*][*]presets[/*][*]startup[/*][/list][/list]
This way i can have fully portable Blender, even several OS version using the same addon folder (the Scripts folder is like the one that is in the Blender installation). No need to duplicate addons accross Blenders
Blender File Path Docs
I see no reason why to use this path specifically for Verge. Even the fact there are executables inside. UV Packmaster, Quadremesher and others have executables too, and still don’t use this folder, and even let you choose the path to it.
Edit: Will reformat the list later
