Thank you for your feedback on the Persist Bitwarden UI and maintain unsaved data issue. Bitwarden is aware of and working to address this issue. The new design does include a persistent “popout” button across all screens to ease the issue in the short term. The full solution we are working on will involve temporarily saving entered data if the extension is closed while creating or editing an item.
