The tracker still isn't great, but now in game there's very obvious signs when there's events left undone at your current time of day. Like a big speech bubble and a girls face and a big exclamation mark in it on whatever door you need to enter to trigger the event. And to let you know to look around there are other symbols on screen to tell you something is happening in the academy. Once I think I've tried everything, I just skip time through a full day to make sure I've got everything.
So yea, it's far easier now than it was before
