Is there a way to increase the font size within the application?  It's awfully hard to red the tiny lettering.  Is this a QT application?  There have been a number of similar problems with QT on hi-def screens.  I have been a qbittorrent user, and it has the same problem.  qbittorrent hasn't solved it - they insist that it is a QT problem, and not theirs.

Found it.  Click the little gear icon in the toolbar.  Settings comes up, the third item in the left pane is fonts.  Increase size a couple numbers, click accept, changes take place immediately.  Default size was 9, I think.  At size 16, my desktop looks good.
