I’ve been enjoying Goodnotes for most of my classes, however I find when it comes to taking notes for my electric circuit analysis classes, my drawing ability on a tablet starts to lack. So I suggest including symbols for general ECE components into the shapes library OR have an option to create custom shapes (more applicable than just ECE) that could be added to the shapes library. I enjoy the shape-snap function because it’s quick, and I need that for those fast paced lectures.
