Looks like nothing is stopping you! I thought we were supposed to calm 
down on features...

In libreoffice I see two difference that are IMO very useful:
1/ the zoom value is shown beside the slider. Seeing the zoom is very 
useful. At the very least, the tool tip should show the value instead of 
explaining what it does.

2/ having a small vertical line at the default level is nice.
