Mismatched fonts

[icherny44]

There's a mix of serif and sans-serif fonts in headings, plot titles, axis labels, menu names, etc. This isn't exactly a bug, but the tool would look much nicer with a uniform font family. Also, there are a lot of different font sizes. Consider choosing a limited number of larger fonts to emphasize the most important headings and information (see screenshot).
