[Q] Remove menu padding/spacing in ICS?

Hello. I just moved to ICS, and I'm doing some modding in it.

There's one thing I don't like and that is the spacing/padding on the left and right side in some (most) menus.

Does anyone know how to remove this?

Let me illustrate with a mockup:


The left is how it is, and the right is how I'd like it.

It is ofcourse also very noticeable in the Settings menu:


Any ideas?

Thanks,
