Feature request for Zextras Backup

Hello guys,
one small feature request that might help ppl like me using Zextras Backup.
Many time I have ppl asking "I deleted an important e-mail, my life depends on it!" so I say " Ok, what message was that?" and I get "Hmmm... let me think... something about this project.. it came from a Tukish address, no, maybe a German one.... but it was important you MUST recover it!", and so on.
So my request is: why don't you add an advanced search fuctionality that might search inside Zextras Db in order to find specific email messages?
Not a simple task I know, but it would make a lot of sense in order to avoid undeleting hundres emails to find hust the needed one, it might even be an hook for a "self-restore" interface.
Thanks

Alberto
