Overview:
km_connectSyFields allows you to easily connect/disconnect existing fields with existing cloth objects in Syflex for Maya.
(Obviously you need the Syflex plugin to use this script.)

Usage:
Fields are listed in the left column, cloth objects in the right.
To (dis)connect, simply use the appropriate buttons at the bottom.
Use the right mousse button of either the fields or cloth to display extra functionality
like open attribute editor, open the syEdit window and refresh the UI
(for when you create new fields and/or cloth while the connectSyFields UI is open).

Installation:
Source this baby.
