Yep, send feedback to them as well. Love the undelete function and the silencer... please keep in mind to check the undelete function from time to time, since it holds back at least 20 (or was it even 30) of your emails/messages/contacts from being wiped.
So what does that mean? After undeleteing 20 messages, it's not going to work anymore?
No, not at all, but to limit it resource consumption they only 'save for undel' your most recent 20 messages that you have deleted. So older ones will be replaced by the newer ones - so a kind of 'first in - last out'
