Describe the feature

Simply I'd like to copy categories from my main account to my second account. I've tried copying saved variables, I've tried searching multiple sites and multiple phrases and I still can't get this to work.

Describe the implementation

Ideally, there would be an import/export categories in the addon.

I agree that Import/Export should eventually be a built-in feature.
For now, you can use this plugin https://github.com/zeptognome/BetterBags_ImportExport
