Proposal:
When creating or editing a text document in Proton Drive, users currently have a limited set of typefaces compared with the richer font selection available in the new spreadsheet editor. To provide a more consistent and flexible writing experience across the suite, we propose extending the text‑document editor to include all the fonts that are now supported in the spreadsheet module (e.g., Calibri, Cambria, Arial Unicode, etc.).

Benefits:

Unified Design Language – Users can maintain visual consistency when embedding tables, charts, or excerpts copied from spreadsheets into documents.
Improved Productivity – Reduces the need to switch between applications or manually adjust formatting after pasting spreadsheet content.
Enhanced Creativity – Offers a broader typographic palette for reports, proposals, and other professional documents, aligning the text editor with the modern look of the spreadsheet tool.

Implementation Considerations:

Sync the font library between the two editors, ensuring any future font additions appear automatically in both places.
Preserve existing document compatibility; default to the current font set if a newly added font isn’t supported on older clients.
Update the UI to display the expanded font dropdown without clutter, perhaps grouping “Spreadsheet Fonts” under a dedicated sub‑section.

Conclusion:
Integrating the spreadsheet font collection into the text document editor will streamline workflows, enhance aesthetic control, and reinforce Proton Drive’s reputation as a cohesive, privacy‑focused productivity platform.
