I second that request. I've been attempting to use the hex grid to do wilderness based hex-crawls, and the current FoW reveal capability doesn't really lend itself to revealing a single hex at a time, which I believe is the norm for that type of play style (at least based on the majority of google searches I performed a while back when I was trying to get the basics of hex-crawl style play). The current system works great for dungeon crawls for me, but having this option for overland wilderness based adventures where you truly only want to reveal one hex (not square) at a time would be a huge benefit.
