As an alternative to codeblocks, having a way to paste something into a point without having to create a point, enter into a note, and then paste in (and format) text that is a code block would save a lot of time. Even if it’s just a way to make a new point and jump directly into the notes, that would work.
After pasting in the content into the notes section, the user would fill out the point with text describing what the block is about (since they can’t leave it empty).
