Auto-numbering, card scenes

Hi.
I thought I saw a reference about the possibility to have automatic card numbering in the corkboard view (thewritepractice.com/storyboard-in-scrivener/). But I can’t seem to find it in Windows.
Is it a Mac-only feature?

The auto-numbering option for the corkboard is currently only in the Mac version, yes. It will be part of the next major update.
