Enhancement: undelete and recurring events

I have used this simple and effective plug-in on many sites for several years. It is important that a site’s Events page not have out-of-date events on it. This plug-in does the basics superbly. Here are two enhancement suggestions:
1. Undelete function
The user can accidentally delete an event, especially if working on a handheld. Let’s get a recovery function programmed into the plug-in.
2. Recurring events
If, for example, a site has an event that occurs every Wednesday, or the first Monday of the month, or something similar, it would be helpful for the plug-in to enable recuurring events between a specific date range.
