There is no denying media plans can get big and difficult to view. And when a media plan contains a lot of packages, it's even harder. You now have the ability to collapse packages to hide the associated placements from view until you need it.
In your media plan click on the package icon to collapse it.
Once collapsed the individual placements will be hidden and a number indicating the amounts of placements in the package will appear. Now you can view more details in your plan at once.
