In keeping with the portability XYplorer offers, I think it would be great if there was a folder
XYplorer\data\fonts
for carrying around fonts. Fonts in that folder would show up as options in Configuration\Styles and Colors\Fonts
Personally, I use FiraCode for most of my work, and would like to use it in the list view as-well. However, it's not installed by default and therefore am dependent on the machine. Most everything else in XYplorer is portable, so having fonts be as-well would be great.
This was requested nearly a decade ago, though it seems like it wasn't considered; Portable Fonts
