Icons are scaled in world space

When using sprite components on items in the editor, icons need to be scaled appropriately to match the viewport (i.e there should be a consistent maximum size in screen space).

I’m currently using the landscape tool to do some smaller-scale work (tens of meters, rather than hundreds), and I’m finding the gigantic, obnoxious icon that is some ten meters across is making my work incredibly difficult:

I’m not entirely sure how to have the icons automatically scale relative to the screen, but you can manually scale these icons by going to Editor preferences > Billboard Scale
