About the little scrollbar arrows...

...is there any way to get these back in Mac OS X Lion? Or do I need to downgrade to Snow Leopard just get these seemingly trivial but for me necessary things back?

Lion as a whole is a fine thing but this particular problem doesn't swing with me. Apple could just as well have left the option in the Preferences and I have no idea why they decided to remove it altogether. Not very intuitive IMO.

I work as a graphic designer and use Photoshop every day. Many files contains hundreds of layers and I really need fine control over the layers- list. Without the arrows things have increasingly become horrible, it seriously messes up my workflow. Yes, I can use the trackpad but that isn't the optimal solution for me since I use a Wacom tablet. Every time I need to bump up a few layers I automatically use the tool I have in my hand, i.e mouse or pen and it's really hard to pinpoint a specific layer many times. It's extremely annoying so I wonder if anyone know how or if there's a possibility of getting the arrows back?
