In KDE *Kubuntu*, how do I resize the widgets in the panel?

I had a bit of problems with Ubuntu 11.04's Compiz restrictions so I decided to go try Kubuntu. After moving the panel and adding Docky, I'm more content than ever. It's not exactly GNOME2.3 but it's the next best thing. Any way, as happy as I am with Kubuntu right now, how do I resize the widgets? For instance, the CPU Monitor, I can only place it in the system tray, and in order to separate it from everything else, I have to add a huge spacer. Thing is, I can easily change the spacer's size, but I can't find out how to change the size of the CPU Monitory. I like having it like I did in GNOME2.3 where I can easily see my CPU usage. How do I do so? Also, any other tips?
