I will be honest here with myself and say that I hadn't considered how a Challenge Log entry would be good as well, but I will also say that I have been advocating for a long time for achievement progression to appear on the HUD akin to quest progression. This wasn't a request for yet another window or notice tab to clog up the screen, and worse being unable to remove the notice tab (at least on ps4), but then we got the new windows or tabs telling us we're approaching whatever chievs. I agree, though, with including the challenge log entries in the ability to track along with quests or duties.

It sounds like such a simple idea. We need it, both in or out of Eureka. =p
