Allow a custom item type to be copied so that it can be used several times without having to recreate all of the fields for a custom item type you have already created. I created a new custom item type called Vehicle and included VIN, Make, Model, Year, Purchase Date, and Licence as fields for this new custom item type. Since I can't reuse the custom item type I created, I have to create it again, and again, for every vehicle I own. Proton Pass item types would become too cluttered if it provided every conceivable item type users want, but if users could replicate custom item types, users could tailor Proton Pass to meet diverse user needs.
