SF Symbols variables customization (like the color)

[ZeKap]

Hi!

I wanted to create a plugin with an icon for the wifi (in my example), but encountered an issue: the SF Symbols don't have different variants for an icon. For the wifi icon (in my case), they use the color variable to render more or less wifi signal:

In this example with the color variable it's one bar at 1%, two at 33% and all three at 67%, so 50% give two bars.

I would like to keep the SF Symbols for consistency as I'm using other SF Symbols for other plugins, and I think they fit MacOS better than Nerd Font.
But as I was exporting each variant in the SF app, I saw that it would be hardcore difficulty to use png AND icons (without needing to export other icons when replacing the wifi icon for something else).

I dont really know how it would be possible to add this to sketchybar honestly, but I would love to see it coming.
