Making LO look nice

Not sure as to what you're referring, but if you don't like the
font, just click on that setting & choose one which suits you for your
purpose; if you don't like the background, you can change this as well; ...
etc. ... just click on the various settings & choose what suits you.
          this would apply to both Impress & Writer.

       Hoping this helps,

Is there somewhere I can post a screen grab to explain it better ?
