Layrs 1.1 PS extension (free)
Layrs 1.1 is a free Photoshop extension - a collection of scripts by wonderful developers combine in one ps panel/extension in hope to make tedious job of working with layers a bit more easier.
Thanks to those great developers Paul Riggott and Jeffrey Tranberry for permitting me to use theirs scripts in that extension. I urge you to visit their sites to see other cool scripts.
Features:
1) Layer name editor
2) Remove unused layers effects
3) Flatten all layers effects
4) Delete empty layers and folders
5) Rasterize all smart objects
