Migrating from KeepassXC, running into issues and questions

Hello AliH1P, thanks for the heads up. In the meanwhile I've cooked up a very crude command handler by running a small Flask app on port 5000. The Flask app renders a form with some small Javascript that autosubmits the form with a POST request. I have 1Password autofill that form to http://localhost:5000/ and with the help of Jinja2 the Flask app renders a working command from the form data which is then being executed by the subprocess module. Another option would be to create my own Firefox extension and use the native messaging possibilities to try interacting with the 1Password extension. Maybe something for the future.

Also, after doing a clean Xubuntu install 1Password now properly locks when I lock te screen. I think that with the other install with the non-locking 1Password I did something with the screensaver that caused 1Password to not lock on locking my screen.
