>>>What must I do if I don't use this system of library?


You can create it by hands, when I have no Custom UI Installed I created simple plans and use them as labels.
You can use for labels any object that you want it can be plane, box or even sphere :)



>>>When You Reset CPlane by Menu, that don't erase the Cplanes Style!
Does this normal?

Yes it how it should be, it is the main idea to keep all labels and CPlane style. It is like repository of CPlanes.
