Tabs on top?

I posted earlier something about this in for Defraggler, but felt it would also apply to CCleaner as well.

Firefox has tabs on top, which is a TON better than the amount of space it took up earlier!

Any way to include (at least the option of it) for tabs on top in CCleaner?

Man, I would LOVE the extra space on the side I had!

When you have tabs on the side, seems to take up so much room!

Tabs on top could be much slimmer, since they can be just over the size of the text.

Current tabs on the side look good, but they are 4 times larger or more than the text they represent!

With tabs on top, the screen real estate would be used so much better because far less space would be wasted!

I think this was suggested a long time ago, but I don't quite recall. I sort of like the idea, much nicer for people with low resolutions.
