How to set the GH Panel default font / size?

Somehow my GH panel default font / size got out of whack. Where may I be able to reset / set that?
I can set the individual panel, not the global / default. See image:

Im pretty sure you should be able to right click the panels and set the font type, size and etc.

@Anton The GH plugin MetaHopper has a tool for that called “Set Panel Properties” that could be a possible solution. It’s got many amazing tools to control gh properties with gh components.
