That would become quickly unmanagble as the document got longer. I can't image trying to deal with a separate set of layers for each of the 200+ pages in one of my catalogs. Easier to lock or turn off individual items or groups.
That's much like stating that master pages should be improved, because every time you use one it displays the same. Or paragraph styles should not be the same, each time you apply them to some text. Or ...
The mind reels. How would you switch off one layer document-wide? Suggest an improvement that makes them document-wide again?
Hi there, Photoshop user.
It must not work like that. Better way is every page to have its own layers and the problem will disappear.
You can change the stacking order of objects by clicking on the little arrow in the Layers panel:
so that you can see each unique item on your page as if it was on its own page-specific layer:
So, if you need to lock a single unique item, or a bunch of unique items that are only on one page, you can do that here, as if the layer were a page-specific layer. See, it already works the way you want it to!
