XSI-like hide toggler. Hide and unhide only last selected object (in our case last named object).

script: /*HIDE*/ var selobjs = moi.geometryDatabase.getSelectedObjects();if(selobjs.length > 0){var allobjs = moi.geometryDatabase.getObjects();for ( var i = 0; i < allobjs.length; ++i ){var obj = allobjs.item(i);if(obj.name == "lasthide")obj.name="";}selobjs.SetProperty("name", "lasthide");selobjs.SetProperty("hidden", true);}else{moi.geometryDatabase.selectNamed("lasthide");selobjs = moi.geometryDatabase.getSelectedObjects();selobjs.SetProperty("name", "");selobjs.SetProperty("hidden", false);}
