Scattered throughout the various sub forums are numerous examples of LTspice files with circles and arrows and a pargraph about each circuit, Much like the completed projects forum it would be cool to have some of them collected and organized not only for the circuits, but for the techniques like testing device parameters against the datasheet and using the various capabilities of LTspice. The big advantage this forum has over the groups.io site is the ability to combine files with images and pictures.
