Glimmer Board turns Chrome's New Tab page into a private spatial board.
Add notes and widgets, arrange separate spaces, and switch between Edit and Overview modes. Settings includes export and restore for backups you control. Nothing syncs between devices.
If the board does not render after an update, export a backup before clearing extension data, then reload the New Tab page. Glimmer Board has no account or recovery service and is not an emergency or clinical communication channel.
