A TWoS Manual would be the best ever add-on for this mod, and SH5 in general
A good description about the TDW interface and all the scrollable instruments and tools, plus different possibilites to setup the game (in the OFEV, in the game itself) would be enough already, other things are already well-explained in the numerous single docs that come with TWoS.
But a traditional pdf manual with all-in-one information also with nice and helpful images, that would be great.
