1. One or more computer-readable media having computer-executable instructions embodied thereon that, when executed, perform a method for automatically manipulating properties of resources residing at one or more locations targeted by a library, the method comprising: receiving a user-initiated operation to launch a library, wherein the library comprises a framework for contemporaneously accessing the resources of the one or more targeted locations within a scope of the library; incident to launching the library, surfacing representations of the resources at a UI display; receiving a user-initiated action applied to one of the surfaced representations; in accordance with the user-initiated action, automatically manipulating the properties of each of the resources residing at the one or more targeted locations within the scope of the library; at least temporarily storing the resources consistent with the manipulated properties, wherein storing comprises updating a library-configuration state that captures qualities of the resources upon manipulating the properties thereof; recognizing an extension of the scope of the library to encompass a subject resource residing within an untargeted location; and incident to recognizing an entry of the subject resource, automatically manipulating properties of the subject resource to align with the library-configuration state, wherein the library-configuration state of the subject resource is consistent with a latest manipulation applied to the resources originally provided within the scope of the library.
