I really enjoy using ONLYOFFICE Sheets and find it very powerful. I wanted to suggest a feature that I think would improve workflow for users who work with multiple spreadsheets simultaneously:

Feature Idea: A shortcut to close all open sheets at once while automatically saving changes (similar to Excel’s Shift+Close behavior). This would save time and streamline managing multiple documents.

Thank you for considering this suggestion, and for your continued work on ONLYOFFICE!

Best regards,
