FYI - I'm working through many of the fonts and color choices on this system. Some are too dark background you can't read and other times the font seems to disappear. If you spot something reply to this thread and I'll work on fixing it.
I dug into this and the new version of the Xenfro software 2.3 will have a dark mode with an automatic switcher for the user. It is being beta tested right now. I'm going to set the background to a lighter gray for now which should help and hold off installing a third-party night mode plugin for now. Hopefully the new version gets released soon.
