Wish code editors would support different fonts per semantic region. Jetbrains, if you are reading this, implement this: <https://youtrack.jetbrains.com/issue/IJPL-29552/Allow-differ...>.
The heading of Iosevka doesn't do the font right, my first thought was that this would be yet another soulless sans-serif. But it has tons of interesting variants. Hats of to Iosevka Etoile. See also <https://monaspace.githubnext.com> if you like big versatile font families.
