I looked up the forum and I saw someone asked a similar question before but I think they were misunderstood.
Currently, I have completed a project (P1) but I want to updated it without loosing my previous work. if there was a "Save as" option I could save it in a different name (P2) and I will get to keep the old project (P1) meanwhile I can work and edit new project (P2).
Currently if I edit the project (P1), it will rewrite it. The best option is to create a new project and copy everything I did from he old project to the new project. That includes manually entering each variable I used in the previous project.
if there's a better solution please advise. But adding the Save as button will be great.
Thanks in advance
