You can name the files whatever you want and put them in whatever kind of directory organization you want. You can also use multi-line mode to store additional information. (One thing I suppose I should add, then, is the ability for the clip mode to only put the, say, first line on the clipboard.)
Alternatively, and perhaps this is cleaner and nicer, you put the password in Amazon/bookreader and the meta/additional data in Amazon/bookreader.meta. Or come up with your own scheme that works for you. The system is really flexible.
Is it flexible enough to support separate fields? Having a multi-line "password" is kind of ugly... And if I want to save security questions, username, password and email, I'd need at least four files?
It is flexible enough to do anything at all. It is super duper flexible. There is no enforced scheme or organization. You can do things how you like.
One possibility I listed before was:
Put your password in Amazon/bookreader and the other account information in Amazon/bookreader.meta. Then, this would be the case:
$ pass Amazon/bookreader
23nauDSJ92*#@nb23b2
$ pass -c Amazon/bookreader
Amazon/bookreader copied to clipboard for 45 seconds.
$ pass Amazon/bookreader.meta
Secret Question 1: Dog's name? Oliver
Secret Question 2: Do you understand the concept here? I hope so.
The point is, you can organize things however you like. You don't have to use this scheme; you could use a different one.
