This is something that has been asked for before on PC, but was never granted as far as I know because of the lack of attention to it from the player base.  If you feel like this is needed please give a reply to let the GMs know its important to you.

It would be useful to have a counter letting you know how many of a certain enemy you've killed when grinding for titles you want to achieve.  It would give some much needed motivation, since seeing how far away you are from a goal can help you decide if you want to spend the time going for it or not.
