Every time I make changes to any of our recurring events, I'm scared that something goes wrong and the whole recurring event will get deleted, or somehow broken.

If you look at Google Calendar fox example, they do a very good job in supporting Undo actions. Every time you do something - add an event, delete an event, modify an event - you can take the action back. They display an information bar above the calendar like this:

{{{
A new event NAME was added for DATE:TIME.
}}}

That is awesome and people don't feel threatened by either their mistakes or programming errors, because they can always undo the last action, if it goes wrong.

Can we implement something similar?
