I use Photoshop for digital scrapbooking. When I select a layer in the layers panel, on the desktop version, the element on my 'page' is highlighted. It doesn't do that on the iPad version. There is no way for me to know which item belongs to the layer I've selected. I've googled, but can't seem to find much help when it comes to using Photoshop for scrapbooking.
Are you referring to View > Show > Layer Edges in Photoshop on Desktop? At the moment PS on iPad is very light on preferences. The only way to know which layer you're on is to look for the blue outline on the list of layers. Is the mini image in the layers panel not big enough to know what you have on each layer?
