Yosemite: Spotlight window small - resize?? Very unergonomic!

Hi,

after installing Yosemite it immediately started to annoy me that the new spotlight window is so small, vertically. Spotlight used all available vertical space before to list things and now this.

When searching for some PDF for instance one now has to scroll down the list on the right manually A LOT sooner than before, since the list is so small. All this space around this tiny search window is WASTED.

This is inefficient and far less ergonomic compared to the old version.

I've looked everywhere but can't find any option to change this screen centered space-wasting spotlight window to something more useful. Even the horizontal space could be used better ... larger preview for instance.

Is there any way to make the search window larger or revert to the old fashioned list on the right?

I'd be grateful for any help. Since I have tons of documents this wasteful GUI forces me to manually go and scroll through this list a lot more often than necessary if the list just stretched across the screen. I'm fairly certain this won't just bother me.

kind regards

Andreas

PS:

Apple has a habit of breaking stuff which worked really well. Many of the GUI features got broken through the process of supposedly improving things. Exposé/Command Center is a another example of wasted space these days. Back in 10.4 windows filled the available space as good as possible... not anymore. Now Spotlight.
