I agree with both these suggestions. I had to make a newspaper article for school a little while back, and, being the paint.net loving person that I am, I decided to make it look as realistic as possible by doing it on paint.net. Newspapers' text is always justified (for those who don't know what that means it's when the text is arranged to where it makes straight lines on either side of the column), and that was difficult to do, so I had to settle for "aligned left". Most programs that deal with text has this feature, so it'd be nice for paint.net to have it as well.
I like the second idea as well, though, like Steve said, the first one is a priority.
Edit: Oh, and welcome to the forums, Steve
