Change width of rich text cells in notebook
With the default settings, cells in the notebook take the whole width of the window. This is annoying for rich text cells with long paragraphs, as they get very hard to read. Also if you are using LaTeX math mode, the equations will be centered on the window, which looks bad if you only have rather short lines of text surrounding them.
I would like to know if there is a way to restrict the width of the rich text cells, such that lines of text get broken earlier and readability is improved. The settings contain an option for number of word wrap columns, but it seems to have no effect whatsoever on my worksheets.
