Still testing all the alerts, but a new style that's interesting is that I have BER-FRA-CPH-SFO departing 0945. MCT at CPH requires I arrive by 1435.
So I have an alert set for BER-CPH departing 0946 or later, arriving CPH by 1435. So if anything "better" becomes available, I'll (hopefully) get an email.
Edit: There are definitely reasons I haven't made this public. It's quite broken
