Thanks dev, I didn't realize ChatGPT actually knew Regex I just assumed it would do its usual trick of lying kek
As I remember it, there was no saved pattern, I just exported and added [all tags] or whatever to filename, maybe ticked some box or filled some text field to set the separator character, and then there was a similar tag recovery system on import using the same interface essentially. I may have hallucinated this or it may be long-orphaned, this was quite a while back I last tried it out, I think back then I had suggested a system to add a character to separate namespaces from their tags so the system would recognize them on reimport.
Anyways I'll be sure to give your regex a try.
