Yes, this definitely improved the situation, but I think there is still big limitations on what you have access to. Perhaps some of the entries are not marked as web passwords, and/or it is limited to the passwords Safari has saved (Chrome or firefox passwords would get ignored for instance). I have hundreds of entries in my keychain and "Other Passwords..." won't display most of them. As a behavior, it doesn't bother me much if Safari wouldn't get automatic access to other apps' keychain entries or generic passwords (from a security perspective it's a sensible limitation). Instead I would like a separate keychain app, mirroring the abilities of the OSX app.
