Addon Settings

Toggle Option Location
Change where the target folder selection is located. 1st option is next to a vertex group or folder; 2nd option is under the entire list

Actions

Add/Remove
Add a new vertex group or remove the active vertex group or folder. If you remove an open folder, its children will become a child of the folder the now-removed folder was a child of (they will step down in the hierarchy). If you remove a closed folder, the folder and anything inside of it will be removed

Up/Down
Rearrange the order of vertex group or folders. An item may not be moved outside of a folder it belongs to, or into a folder it doesn’t belong to

Add Folder
Creates a ‘Folder’ object inside the list of vertex group, which can have vertex groups or other folders put into them to create a structured hierarchy

Folder Toggle
Open and close the folder. Closing a folder hides everything inside of it, for a more tidy UI
