Other apps have figured this out, and it can work with more password providers than 1Passwd too, so get on it, Airmail!

Agreed. When I try and add an account via iCloud sync, the 1Password icon is there, but when I press it, it only shows about 5 random accounts, none with URLs associated with them, and of course, none that have anything to do with email. There's no option to search, and no categories or other ways to navigate through the usual 1Password panes. I have to manually go to the 1Password app to copy and paste the password.
