I've a couple of questions regarding the keyfile:
1. Will the Android app support creating a keyfile?
2. Why not allow the user to use any file with random content as a keyfile? I've been using 2048-bit private key generated using ssh-keygen as my keyfile with Keypass2Android.
I recently purchased Enpass after testing the previous beta version. I am really happy with the progress you guys have made from version 5 to 6. I would request you to please include a black theme for amoled displays, just like safeincloud.
