Hover to the left of any of your headings in notes to hide that section. This will help shorten your note and show only relevant info you care about.
Bonus Feature: when your headings are collapsed, you can drag n' drop the heading along with all of the hidden text in that section!
How to collapse your notes:
First, create header sections in your templates or notes.
You can add an H1 or H2 by highlighting the text and using the formatting toolbar or the shortcuts -
H1: Type # and press space, then type your header
H2: Type ## and press space, then type your header
To collapse or expand the sections, click on the arrow to the left of the header.
