[Users] extending/altering GeoExt?

[William Kyngesburye]

Related to my checkedGroup question earlier...  I found that I can deselect all items in a checkedGroup if I remove the "enforce at least one visible" layer check in LayerNode.js.

Rather than hack GeoExt, I figure it's best to somehow extend the geoext tree layernode.  I see there are "plugins" - would this be the way to do it?  Where is the plugin API documented?

Or is it a simple matter using Ext.extend (like geoext does) on the geoext layernode and overriding the enforceOneVisible() method?

Both options are getting into shaky ground for my meagre JS skills ;)
