Rune,
I just checked out your Latest commit, 0.0.10a and loving the fact that on my 1366x768 display I can see the whole screen without needing scrollbars. All the charts size very nicely at font size 7, even with show data turned. I think the pop up windows for Files, Calibration, Display setup, and About are nicely thought out. I wish at some point in the future you could add a setting under "Display setup" that would allow the user to add a centered caption at the top of the graphs for documentation purposes. Keep up the great work!
