When a user renames a calendar in a group the new name should be visible to all users having access to the calendar, not just the user who made the change. Maybe optionally letting a user override the name in his account.
Current behavior: Renaming a group calendar only updates the name for the user who performed the rename. The new name is not visible to other users the calendar is shared with. Unsharing and resharing doesn’t update the name.
Expected behavior: When a group calendar is renamed it should update the display name for all recipients. The calendar name should be a shared property, not a per-user setting.
