Labels for rules
Rule groups are now labels. A rule can have several labels, each with a name, a color and a description. Create one right from the label picker, or manage them all in Settings → Rules → Labels.
Lifetime window
Rules can check spend and results since launch, not only today or the last few days.
Your view is saved
Filters and display options work the same on every list and are kept for each member, across reloads and devices.
Recently deleted
Deleted rules have their own page, where you can bring them back.
