Let’s say, you created the layout and getting prepared to export all the layers for front-end coding. This would take so much time if done manually.
For Photoshop, there are some built-in methods (like an export script). However, Breezy, a free Photoshop extension handles this process nicer.
You can select the layers to be exported and they will be ready very quickly (with the layer names, transparencies, etc.) inside a pre-defined folder.
