3 updates shipped in Pace.
On accounts with a lot of campaign groups, the overview page now shows the ones furthest off pace at the top, so you don't have to scroll past groups that are already on track. Once an account passes 15 groups, a search box and page controls keep the list easy to work through.
Group your campaigns and you can now sort the campaign table by how each group is pacing, most overspent or most underspent first. Click the Group column header, or use the new sort menu, which also covers spend and name. Useful once an account has a handful of groups and you want the ones furthest off plan at the top.
When you add campaigns to a group, the picker now pulls your full campaign list straight from the ad platform, the same list you see in account settings. Campaigns that are paused or haven't spent recently show up too, so anything you've included is always there to pick.
