I used a lot of LATEX to write long texts but now, I have pretty much switched over to use notes in the Brain.
One feature, however, I truly miss, is the possibility to hide text.

In Latex, whenever I put a % sign in front of a line of text, the paragraph will not be printed, the text is however still there.

Why is such a feature interesting?
I am writing a text that later I will print out as a pdf and hand out.
% I work on the tex for a long time and put in ideas, cancel out old paragraphs, write down text fragments.
I do not want to see these ideas and fragments in the final text but I want them to be IN my text so that I can keep working on them.

Please, do implement a way to hide text in the print-out but keep it in the notes.

Thank you!
