I might be unaware of this feature existing, I would like to take my latest project and make a duplicate (clone) so that further feature addition and ckt editing can be done in a separate file, in effect creating a versioning feature in easyeda. I currently have to create a new project > create a new schematic file in project > copy paste schematic from separate project > rename components (they get jumbled during copy paste) > add new features. This takes too long for any professional job. Please consider adding such a feature, or let me know if better procedure already exists.
