Hi, Yesterday I had to do some minor changes on my PCB due to changed components. After each change, I create a backup of my project, which is tied to the specific HW revision. I did the changes to the PCB, created a backup and was finished for the day. Today I opened EasyEDA Pro and the changes I made are not in the PCB, however the backup does exist - when I open the backup, it contains all the changes I did. But to open the backup, I have to create a a new project or save it to an existing one, which however does not contain the previous history. I need the history and so this is not a viable option. Can I somehow apply the changes from a backup to the current "head" of the project or is this not a possibility and must I manually do the changes again?
