What if we can see only the highlighted text in a note? It will be great for reviewing large chunk of text, but without scrolling the parts that we did not consider important, thus keeping the gist of it. Great when you want to refresh your memory on a topic quickly.
For a better readability, it will be great to keep the headers (#, ##. ### etc)
and maybe get rid of the color of the highlight, displaying like simple text.
What do you think?
