Expanded:

Describe the solution you'd like

I want the SideBar to require either an icon-prop or a shortLabel prop

Describe alternatives you've considered

I tried hacking a function to generate the svg path on the fly, but it started to feel overkill when I had to use opentypejs .. :D

We’ll discuss it in the team, but we’re sceptical to how much value it would bring to have such little space for text labels.
