When overriding a language string it's hard finding a language key. You have to attempt to use the language debugging, know the key, or edit the PHP file. The key parameter could be a Tags usage with a 1 tag limit this way it's just a dropdown with the ability to add new values. It should then parse out the language plugins keys for the dropdown so you can select from an existing key or add new ones, but it'd be helpful to be able to search for a key based off its string. So a new parameter specifically for doing that via ajax could be good.
