In mapfish applications it was the possibility to get an slider control
to change opacity in layer tree, just right click over layer name's.
This bahaviour is very interesting for me, but i'm not idea how can I
reproduce it in geoext 1.0 application.

 

I added it to the layertreebuilder ux (Alexander Dube excellent
creation) using the contextmenuplugin,
viz this edit to LayerTreeBuilder.js

initComponent: function(){
        this.addEvents(this.CUSTOM_EVENTS);

        this.plugins = this.plugins || [];
        this.plugins.push({ptype: "gx_treenodecomponent"});
        this.plugins.push(new
GeoExt.ux.plugins.LayerTreeBuilderNodeAgent());
        this.plugins.push(new GeoExt.tree.ContextMenuPlugin({ 
            sliderOptions:{
                  aggressive: true,
                  plugins: new GeoExt.LayerOpacitySliderTip()
                 }
            })
       );   
 
GeoExt.ux.tree.LayerTreeBuilder.superclass.initComponent.call(this);
        if(!this.layerStore) {
            this.layerStore = GeoExt.MapPanel.guess().layers;
        }

        this.layerStore.on({
            "add": this.onLayerAdded,
            "remove": this.onLayerRemoved,
            scope: this
        });

        this.layerStore.treeBuilder = this;
    },

See http://kite.gns.cri.nz/PBE/index.html#MAP:OPAConfig.json for example
in action.
