Feature Request:
Integrate Proton Lumo as an active sidebar inside Proton Docs and Sheets using the same secure architecture already utilized for Lumo document uploads. Additionally, expand the workspace ecosystem by launching "Proton Slides" with the same integrated AI capabilities.

How the Lumo Integration Should Work (Maintaining E2EE):

Zero-Knowledge Architecture: The AI does not read the document in real-time. Instead, the document remains locally decrypted inside the user's browser/app session.

On-Demand Processing: Only when the user explicitly triggers an action in the Lumo sidebar (e.g., clicking "Analyze this document" or "Generate summary"), the locally decrypted text is sent via the secure User-to-Lumo pipeline to Proton's volatile RAM.

Ephemeral Execution: The server processes the request, returns the output to the sidebar, and immediately wipes the data from the RAM, keeping the zero-knowledge promise intact.

Why this matters:
This eliminates the architectural friction of manually copying text or downloading/re-uploading files into the standalone Lumo app. It delivers a seamless, native "Copilot-like" UX without breaking End-to-End Encryption.

Expanding the Suite:
Please prioritize the development of Proton Slides to complete the core productivity suite. A presentation tool built with privacy at its core—and integrated with this exact Lumo sidebar logic to help structure presentations and format text securely—would be a major milestone for moving away from Big Tech ecosystems completely.
