Improvement to css

Changed log.expanded to 20% instead of 40%, because it popup really big,
and it becomes into an annoyance. The space is minimum, setting it at
20% it looks nice and functional.

The title for plugins like network-information and file-transfer, the
title is too big that it requires a second line to show the title.
