Bitwarden missing key features!

First of all Bitwarden is missing several key features namely:

Actually you can already Increase iterations for PBKDF2. Just log onto web vault

As for 2FA on unlock, it’s pretty pointless since if your device is compromised, and you are signed in but locked on that device, there’s a cached version of your encrypted vault on your device. With the cached information, the attacker can launch brute force attack to try crack your password. Once the password is obtained they can access your vault. 2FA does not form a part of your encryption key and plays no part in encrypting your vault. Its only purpose is to prove you are who you say you are.

As for the other suggestions, I completely agree.
