I don't like putting the private key in the notes field, because its name is still "notes" (but I'd prefer the label be the key's file name), it's actually markdown formatted text, not literal text, and what if I still want to write a note, but I've already used the notes field for the key?

HTTPS certificates including multiple certificate chains, and private keys, and those are all multi line files. And each part should go into a separate clearly labeled multi line field. And I don't want to be forced to write a copy of my server's ssh key into a local file on my laptop in order to attach it to a 1Password file field, and remember to delete it quickly before Time Machine backs it up for posterity.

Right now I am forced to concatenate all my certificates and keys into the "notes" field, and write the file name before each part, and put blank lines between each file, which is terribly inconvenient and error prone.

I also put a multi-line list of all the user names and passwords that I set up on a server.

There are millions of other reasons why anyone might want to use a multi line text field beyond ssh keys and certificates, just use your imagination.

My question is why wasn't this obvious feature supported from day 1, like I fully expected it to be with I bought a 1Password license? Why did I have to find that out for myself the hard and disappointing way, because I never noticed a section in the 1Password manual or promotional advertisements about why 1Password made the decision not to support multi line text fields. I'd love to know the reasoning behind that decision.

[Edit in response to "Maybe I don’t understand, but couldn’t you use the notes section? Wrap whatever you need in triple backticks to create a code block?":]

I PAYED for 1Password, and the company I work for standardized on it and requires we use it, so I kind of expect not to have to jump through those kinds of pointless hoops with a commercial product. I should be able to select-all/copy/paste without meticulously selecting just the right text character-by-character. The time I waste doing just that would pay for a yearly subscription to a better product.
