I absolutely love plain text notes. Maybe you could understand that just because you think something is unpleasant and ancient, the rest of the entire human race might not agree? Shocking I know.
I can't stand any formatting whatsoever on my notes. I love plain text because it stays exactly as that: plain text. I don't want my dashes to be turned into spacers, I don't want my asterisks to be turned into lists, etc...
