We're starting to roll out Audiences.
Audiences let you control who sees your nudges, Questlists, and commands. We're working to bring more compatibility for audiences to all of our widgets, but right now, it's available in nudges and questlists, with commands coming soon. Eventually, the Audiences tab will absorb the existing "Rules" tab so that you can use the same component across all of your widgets to target different subsets of users for different things.
Got any other ideas for audiences we should have built in? Let us know!
