Requires Unity 4.3 or higher.
A simple window to quickly access your favorite assets (scenes, prefabs, scripts, etc.), as well as scene objects, per-scene!
Simply drag'n'drop objects inside the Favority window, click to select, double-click to open: voila! No more scrolling through the hierarchy to edit that manager, or that hard-to-reach object that you constantly come back to.
Note: Favority saves its data per-project, per-user, outside of the Assets folder: no source control mess.
Our code is unintrusive, editor-only, and restricted to our own "Swing" namespace.
