I was doing some changes in some code app for my 3D printer firmware, along with some other dabbling here and there over the years and noticed some of these systems make better use of colored fonts than others.
Today I was trying to help someone else in this community and was typing up the following formula:
I was able to create that by adding a piece, saving it, then looking up the next piece. To insure that every step along the way I had the right bits and pieces, it would have been incredibly useful if each nested function was a different color. So you could keep track more easily.
