It would be awesome if the Proton Pass desktop applications (e.g., Linux, Windows) supported the ability to autofill records via shortcut commands to allow for authentication to desktop applications. Other password managers (e.g., Keeper's Keeperfill for Apps) support a similar feature that allows you to select a keyboard shortcut and automatically insert all specified credential options to whatever application or command-line you specify.

This would vastly improve Proton Pass's usability, especially for Linux or Windows applications that do not render in a browser or allow third-party extensions. Being able to pass these credentials securely through a background service would also prevent potential spyware or other malware from clipboard monitoring or keylogging.
