The Libraries panel (Window>Libraries) is really useful for storing assets that you want to reuse later. If you want to save something that’s on a layer, simply drag it into the current library in the Libraries panel and it will be synced. But what if you have multiple layers and want to save it as a layered document in the library? Select multiple layers by clicking on each while holding down the Command (PC: Ctrl) key, or click the top layer, hold Shift, and click the bottom layer to select all the layers. Once all the desired layers are selected, drag them into the library and a layered file will be created. At any time, double-click on the library thumbnail for that asset and a layered Photoshop document will open. This is a great way to make reusable templates.
