OK, a few more thoughts. It turns out that there's some utility with the time-based filters. I specifically use it when I'm relatively stationary and on a level 100+ land, so when it is set to Day, it renders just what I need without having to switch between map filters, especially when I go after FoT.
Based on that, I would recommend a minor UI change. I feel the time-based filters would be better if it were in the Additional Options menu, adjacent to the Map Filters and Map Style buttons. When traveling, I would switch to disabled mode, and it would make sense to not have to open Profile and hit Save when I do.
Just more thoughts.
