Reverse Layers Order in Photoshop
There is one command which you may not use it often but definitely it is worth to know about. It is command in Layer > Arrange > Reverse sub-menu. To be honest I think I have never been using this command before but I knew about, at least I have idea that command which can reverse layers order in layer stack exist in Photoshop.
Since my layers was arranged exactly opposite of how I need them to be arranged, I start searching for this command in Layer menu (where else?). With wrong arranged layers selected in Layer panel I discovered America or Reverse command in Layer > Arrange sub-menu. It works and it saved me time to drag (Ctrl/Cmd + ] or [ ) layers to rearrange them.
