Hi, i think that it chould be a great idea to add an option that save the history so that you tex: can go back and change... Can se exactly what u have done with ur project...(all the history can do...)All this after u have close PDN and then reopen ur project. Because of what i know, the history is gone when you reopen PDN. Is this possible?
//sorry for my english, hope you know what i mean.
