For a few years now, I have kept my daily scribbles and volatile tasks using the classic Macintosh application Note Pad, it's a very simple program that does just about anything one might want from note taking apps. I haven't done any changes to it except:
- Double-click selects a whole line, so it's easly to erase a whole task.
- Draw lines starting with a dash or caret with a little indent so it's easier to read.
- Various fixes to word selection.
- A pen mode for quick doodles.
