Great to hear the KISS perspective! With you coming from that perspective, I would be genuinely interested if the “basic use” of Anduril does anything for you.
This “basic use” is Click (1C) and Hold (1H) (plus release and hold again). As the manual states: “That is all the user needs to know for basic use, but there are many more modes and features available for people who want more.” This might take away the perceived complexity and just leave the flexibility of Anduril. I have taken a shot at visualizing this “basic use” by placing it in the very center of a diagram:
As to the diagram: For you coming from a KISS perspective, is this kind of visualization of help, or is it just intimidating once again to look at the entire one-page diagram? And if you are visually interested at all, would you have any suggestions on how to better accommodate the KISS school of users?
