A suggestion/request for the Cheatsheet. It's great, but I'd suggest removing the graphic of the different dice types and instead add a small paragraph explaining Feats. That seems to be the main mechanical element that I immediately felt was missing when reading through this. Similar to the Gambits section, I don't think you have to list out all of the options - it can just be a brief overview of Feats indicating they exist as a combat option and that they'll require a Save or you become exhausted and can't use another.
