It took me almost 20 years before I really discovered the advantages of layers in digital graphics.  For so long I'd treated computer graphics as just another form of 'painting'...doing 'everything' on the one layer [background].

PSP and PSD files are so much more fun...and easier too.

Here's a recent graphic...relatively simple....currently made up of 11 layers [not counting the zorder layering of compound images within the sim's 'panel' ...

yep... working in layers is wonderful... so much more control....

some of v's psd files..... I've stopped counting at about 250 layers.... they are diabolical to look at... and turn off layers to see what disappears... (he doesn't name his layers)...and the huge amount of detail that goes into building up an effect.... viewing one is like peeking into a master class in PS...

Having worked with vStyler's WB's I can attest to that fact. I usually try to group the layers according to function, like the task bar and start menu. But sometimes you can click on the layer's thumbnail and it says..."the pixels are less than fifty percent selected and will not show"...or something to that affect. Maddening.
