Multi-layer renaming
You can now select multiple layers and use Edit > Rename (⌘R) to rename your entire selection, with support for modifier tokens and optional matching of portions of the layers’ names. You can also use Edit > Rename All (⌥⌘R) to rename all the layers on your current page, with the option to filter for specific layers to rename. Finally, you can quickly rename another selection of layers using the last renaming pattern you used via Edit > Rename with Last Format (⌥⇧⌘R).
