Well, it has been a while, but this improvement is now available in version 10.1.5 (Pro and Ultimate only). To update, click the "Check for Updates" command on the Help menu.
When an event, task, or note is right-clicked, there will be a "Locked" option on the popup menu. Clicking that option will lock the item, preventing it from being edited or deleted. To unlock the item, right-click and toggle the "Locked" option off.
There's also a "Lock" button on the toolbar at the top of the Event, Task, and Note Editor windows. This button can be toggled on or off the same as the option on the right-click menu. For example, if you open a locked event and need to make changes, you can temporarily disable the lock via the toolbar button, make your changes, and then re-enable the lock before closing the event.
This feature works in conjunction with calendar sharing. When a shared event, task, or note is locked, only the creator of that item can unlock it. Other users, even those with "Contributor" access, will have read-only access to locked items.
Thanks again for the suggestion. Please let me know if you have any other suggestions.
