Rename Layer/s is a replacement for AE's renaming. Because Workflower uses spaces within the layer name to indent the layer, you would always have to hit Refresh Layout after using AE's renaming function to indent to layer. Rename Layer/s will automatically indent the layers after renaming. Additionally, Workflower uses various special characters around the layer name to display its icons. When using AE's renaming, these icons always get in the way of renaming. Rename Layer/s, on the other hand, strips away these characters.
