yeah I'm sure there's a lot of functions (even really basic ones) that I don't know about mapster either, and I've been mapping for 10+ years, no wonder why most of the mappers still left in the game are all the ones who started toying around with Duke and Build at the very beginning, they learned the basics then only had to learn about the new features of JonoF build, Mapster32 etc... on the go as they appeared, I'm sure it's really confusing to learn how to map for Duke from scratch in 2011, then again back then we had the handicap of not having (or having restricted) internet access so there was much much less info around on websites and everything in order to learn the basics, we had to be passionate and really be eager to learn in order to keep going,
