"At any time during your workflow, you can simply return to the Background layer, make the new layer, and do whatever you need to do. "
I'm not sure if i understood ... does this mean if i open a file and immediately duplicate the solid layer and next 1) add a blank layer and make adjustments there (say healing blemishes) and then i 2) add say an exposure layer (or whatever) and then add say 3) any other layer. If i decide i want to use Liquify now i can just go down to the copied layer just above the locked image, and do my Liquifying? I dont have to flatten the first few adjustments first? all the adjustments remain in the correct place?
