On the Trait Tree Panel, when I select Class Traits, there is (on the right hand side) a tab for trait tree 1 and trait tree 2- what is trait tree 2 for? I dare not click it, because it then shows a warning about "Chage trait tree configurations? All unsaved data will be lost". I have placed all my points in the trait tree 1, in the Bowmaster column- but is Trait Tree 2, in any way something I should use or what is the deal with it?

Thank you
