Thank you for taking the time to review our service and for sharing your feedback with us! The option to pin items is coming to the extension. Moreover, supporting more types of items as well as deeper integration with SimpleLogin is planned for the future. In the meantime, however, we do supporting using custom fields: https://proton.me/support/pass-custom-field. We'll forward your request for supporting the option to generate passphrases to the team, so it can be taken into future consideration.

If you have any additional suggestions for us, you can also contribute to the discussions at our User Voice page: https://protonmail.uservoice.com/forums/953584-proton-pass.
