Firstly I just wanted to say I've enjoyed using 1 password on my Android, PC and iOS devices.
I can't help but feel you have gone the wrong way with auto filling on Android 5.0. I have been using a 4.4 device where it works well but is fiddly (changing keyboards) and I understand why it is done like this. I have been using another password manager on a device with Android 5.0 and it is much more useable. It's is essentially a one touch solution, where you press a button in the notification panel, enter your password if required and your done. With the extra features offered in accessability in Android 5.0 it seems a waste not to take full advantage of them.
Keep up the good work.
