I want a password manager with Argon2 configured to take 10 seconds and 1GB of RAM, playing a gratuitous 3D animation of a vault slowly opening alongside CPU and bandwidth utilization graphs. Or if your attack model allows that reading protected files off a user's device is less likely than the cloud-synced database being compromised, you might derive the master encryption key as KDF_fast(KDF_slow(password)+password)), where KDF_slow takes 5 minutes and is stored on disk, but KDF_cheap takes 5 seconds.
