Is there a way to see when an event was created?
I was duplicating some of the events and now want to get rid of the duplications.
Only I’m not sure which one is the original now.
Is there a way to tell when each event was created?

I once looked into the AT3 file format and don’t remember seeing any information about the creation time of items. Of course I may have missed something, but I think it’s unlikely. It is possible, but not certain, that the order of arrangement in the file is determined by the creation, but that won’t help here. Also, it seems that the order of creation cannot be determined from the displayed event IDs.

But is that even necessary? If you can’t recognize any difference between the duplicate and the original, does it matter which one you delete?

If the original is used in another diagram, but the duplicate is not, you could try to rename the original there, e.g. by appending an underscore to the name.

Yea I deleted what I thought were all duplicates.
Just hope I didn’t delete one that was not a duplicate.
I think I’m good.
I did back it up and can compare it later if needed.
