Need to modify an existing jQuery plugin

We have this gradient plugin you can see here: [login to view URL] if works very well, but we would like to enhance its capabilities: [login to view URL] a reference to the plugin from Javasscript so we can call methods against it (need to a return this to it) 2. From Javascript we want to have the following methods to call on the gradient jquery plugin: A. Add color point from Javascript (% and color of point) after control already in dom (thus we need reference to it) B. Remove all points C. Change fillDirection from javascript D. Destory it (clean all references so no memory leak) All pretty simple stuff, just need to enhance it a bit, Sean
