Shortcuts Suite provides a selection of tools to enhance you Unity3D workflow by help you navigate around your project.
The core of the package is the two new editor windows that provide easy access to your favourite and recently selected project and hierarchy items. These windows allow you to quickly jump between the areas of the unity project you are currently working in and to drag references between items quickly without scrolling and searching.
We have augmented these windows with context menu commands that further enhance your workflow. These provide the ability to jump between GameObjects and Prefabs even on older version of Unity3D, to jump to the matching part of a separate Unity3D project and to control your bookmarks.
We have made this Unity3D workflow enhancement available on the Unity Asset Store here
