Thanks Matt, that's what I ended up with but your example provides an even easier code sample for me to follow.

Sure, you can either make the filter function test more specific
ex: filter:function(record){return record.get('layer').name=="Monday"}
or if you really just want a single layer then, you should use a 'gx_layer' nodeType for a GeoExt.tree.LayerNode

ex: {text:'Monday',

layer needs to refer to either the layer name that you used when you created the OpenLayers.Layer instance or an actual layer object.
If you use a name for the layer attribute, & do not include a layerStore attribute, then the layer store will be infered from the MapPanel's layer store.

I am having a slight issue. What happens if you have 2 layers with similar names like one called Monday and the other called Monday Too. With my loader code below both layers would show up in my layertree evne though I only want the first one (Monday) to show, can it be modified so that it will match exact names of layers only? Appreciate any advice.

            filter: function(record)
                var myarr = new Array();
                myarr[0] = record.get("layer").name.indexOf("Monday");

                return false;
                return true;
