True North Software releases Station 1.4 for Mac, their multilevel (hierarchical) launcher for macOS. Station promotes a more natural organization of applications and documents into folders. With nested folders, you can arrange items in Station in a way that fits your workflow with an uncluttered look and feel. Scalability is greatly increased through logical groupings thus increasing the sheer number of items that can be added to Station without having to shrink the launcher size. Station 1.4 is $14.99 and can be downloaded from Mac App Store.
