Notes are easy to use, easy to format, and really, really easy to read, in 3.0. Printing is the same, so not that great but not less than what we had.
You start out the same way. Choose Insert > Note.
You get a box, and you just type. Note two things: first, just the note box there which is just what you'd expect, but also check out the circled icons. Those icons, the enabled ones such as font and bold/italic/underline, are available to use when formatting the note.
Then you finish formatting, and you could have something plain, or something as silly as this.
If you click on the little black triangle in the lower right corner you get a few options.
And you get those options plus formatting options if you just right-click somewhere in the text of the note.
To print notes, just File > Print, and click the Options button. You can print the notes where you want, at the end or after each page. You can also print only notes.
