Xperia Mini/pro :: Change Just Launcher Screen?

I really like the home screen on my mini pro, but the launcher screen is really annoying. I now have 7 pages of apps, and there is no way to go directly to any particular page.. I am tired of always swiping through page after page. It won't even loop around, so if I'm on the first page and want to go to the last, I can't just go backwards one page.

All of the things I've found to change the launcher also change the home screen. I don't want to change anything but the launcher.Does anyone know if a way to change the app launcher screen without changing anything else? I would love to have the ability to go directly to a page and to have the pages loop.. or, one or the other even. Or else perhaps a 4x4 grid instead of 3x4.
