I actually thought about buying a Wacom, because I make so many small scratch notes I throw away afterwards, to later find myself really needing them again. Besides, having hand drawn diagrams together with the code may serve as excellent comments.

Embedding diagrams in code seems like such a no-brainer. You can do it with a third-party extension in Visual Studio, but it’s still clunky and too hard to use.

This should be a basic thing that IDEs help you do.
