Objectdock: space between icons

Hey guys!

There is a way to add more space between the shortcuts on Objectdock or RK launcher?

The icons looks too close...

I'm searching and searching and nothing found!

And to adding a separator: is terrible, the separator adds tooooo much space!!!

So, I need to add some margin to every icon or something like that?

You could add a really thin separator.

It is still too much space, bu it might look better.

I tried that but is not working...
