This ties in with a similar re-quest on another thread by @sotonin [Name suggested: code repository]. My suggested name was ‘CODEBOOK’ (in the same thread).
Such a feature builtin with the game eases the access for such info/functions. Plus, just log in from any computer/device and the login takes care of all the stored codes. Thus avoiding need to open other tab/equivalent. Perhaps we will get it in time… this is a rapidly developing game after all.
