> A lot more than font was changed, so this may be incidental.
The font change was not incidental; it was filed as a specific issue (JENKINS-23840) separate from the other UI changes. The change submitter also specifically increased the font size.
It appears, however, that Marlene's and my complaints about the formatting of columns are not related to the font change, but rather to the UI redesign, probably pull request 1310, which changed the way tables are rendered.
