This was mentioned once previously (years ago!) but I'll bring it up again. When one encrypts a file, Toucan asks for your password twice, as it should, so you won't have accidentally mis-typed your password and thus encrypted it with some unknown (to you) password. Fine. However, when *de*crypting a file, it also asks you for your password twice! What's the point of that? It's really irritating, and serves little or no purpose. (If it's to discourage password guessing, a better, more standard, solution would be, if a wrong password is entered, delay a second or two or three before saying "Bad password", which would prevent anyone from guessing more than a dozen or two per minute.)
There's really no reason to ask for the password twice on decryption, IMHO.
