The door isn't shut for updates, buying the books for a game I'm not playing just to update the sheets isn't really feasible right now. I was talking to someone on this board about a possible patreon to fund the books and some of the hosting costs, but I've been very busy between family, planning my next campaign, and Overwatch to make anything happen.
What are you using to create the files? InDesign? Illustrator (which would be awkward, but possible)? Scribus?
