I would love the option to copy a password when hitting ↩ in 1Password Mini instead of having to reach for ⇧⌘C. Copying passwords is the only reason I ever call it up outside of a browser. (If I want to “Go & Fill”, I just use Quicksilver.)
A possible alternative would be to allow Quicksilver to initiate copying the password. Then I wouldn’t even need mini.
Semi-related: Maybe take it easy with the “guard rails”. I had to manually edit my 1Password preferences file so I could use ⌘P to call up 1Password Mini. (I use 1Password Mini multiple times daily, but I print less than once a year. I can just use the menu for printing.) Since you’re preventing the use of some “known” keyboard shortcuts, you obviously know what they’re for. What about warning the user and letting them proceed if it’s something they can live without?
