Thanks. Ive been trying to make it intuitive without leaning on tutorials because most people dont do them. The advantage over sheets is that knotend lays out the flowchart for you and is purpose built to be a flowchart editor.
It doesn't have to be a full tutorial of every feature. If I'm going to use the product, I'm going to have to learn the controls. Going through each of the instructions and learning it myself is a bit too much overhead for me. A simple interactive walkthrough of 4-5 of the key shortcuts would really shorten the learning curve.
