How to... manage icons from gnome-shell applications menu?

[Unbr0ken]

Hi there, I have a doubt that I can't solve with google, so, I hope to solve it here.

Is there a way to manage (remove, add, or modify properties) the icons of gnome-shell apps menu?

I've installed PlayOnLinux a few hours ago, so... I need to remove the icons of Wine from the apps menu, but I don't know how to make it. There's no a good reason, I'm just a little aesthetic.

Can somebody help me?, thanks a ton in advance!

-My apologise by the spell mistakes, this is not my native language.-

PS: I'm using Fedora 17 x86_x64 and Gnome 3.4.2.

---EDIT---

Solved, I can manage them by manually at the path: /usr/share/applications.

Thanks anyways
