I was thinking about commenting every block in the ebook sample i made to make it easier for beginners to understand what each block or procedure does. It looks very crowded to me.
There are others ways to use comments, like this for instance.
But if you have many blocks and you want to keep them open then it is also crowded.
If you export blocks to a png the comments are not visible in the exported block.
What commentsystems do you use in your projects to make things clear for yourself or others?
