Everything's too squished together

You know, if you hold control and move the mouse wheel up/down, it'll shrink/expand the contents of whatever you're viewing, be it desktop or the internet.

Or, if you have a laptop, I just use two fingers to drag out/in like you would on an iPhone/iPod.

This, I know.

I just wish I can make things, like the tabs, more compact, rather than smaller. Or make them smaller without making everything else smaller.
