**Is your feature request related to a problem? Please describe.**

The icons in nerd-font patched fonts are too small for my statusbar (in [dwm](dwm.suckless.org/)), and thus I use the following config:

```c
static const char *fonts[]          = {
	"Font Awesome 5 Free Solid:size=14", // prioritize Awesome at size 14
	// fallback fonts at lower sizes
	// ...
};
```

I've been thinking of switching over to nerd-font symbol only, but unfortunately the default is too thin for my liking:

And this is `Font Awesome 5 Solid`:

**Describe the solution you'd like**

It'd be great if there was a ExtraBold variation of symbol only font similar to font-awesome-solid.
