launchpad icons display

Hi everyone,

So I just updated to ML and I was re-installing all my apps.

I realized that the launchpad was organized differentely. Aside from the icons display, the launchpad adds the apps' icons on the first page of the launchpad, when it used to create a second page and start adding them from there....

I like the first page of the launchpad to be exclusively for the Apple apps ; but now, it seems impossible to keep it that way, unless I reorganize the icons every time I add one... Which is a bit of a pain...

I don't know why Apple changed this feature, but I was wondering if anyone knew a way to avoid that....

Thanks in advance!

Chris.
