I would love to see an integration of iOS Shortcuts and x-callback-url in Proton apps to automate certain tasks and streamline workflows. While I’m not familiar with the technical aspects of implementing these features in a privacy-respecting manner, I believe they could provide significant benefits for power users.

Potential Use Cases:
1. Proton Pass:
• Open a specific entry in Proton Pass via a URL scheme.
• Retrieve login credentials for a specific app or website and auto-fill them via Shortcuts.
2. Proton Mail
• Open a specific email thread by its ID.
• Compose a new email with pre-filled recipient, subject, and body.
• Search for emails from a specific sender or with a keyword.
3. Proton Drive
• Open a specific file or directory directly from Shortcuts.
• Upload a file from another app (e.g., scan a document and send it to a Proton Drive folder).
• Share a Proton Drive file via a generated secure link.
4. Proton VPN
• Trigger a VPN connection via Proton VPN when accessing Proton services.

Would love to hear if this is feasible and what potential security/privacy limitations there might be! 🚀
