Remove "story taskbar"?

I’d like to remove the Story Taskbar at the bottom (div#story_taskbar). This thing below:

I’m not an expert at CSS and the best I can end up doing is making it just blank. I know it’s relatively small but I never use it and I’d like it gone so I can get a little extra browsing real estate.

Is there a simple CSS rule I could add (I have the Stylus Chrome extension) to remove it and let the stories fill all the way down to the bottom?

Ideally just remove the “right” portion of it, the part under the stories, and keep the more frequently useful “left” part of it under the folders tree. But I’d be fine with both going away if that’s easier.

Thanks!
Thanks

You can run this custom JS to hide that toolbar:

NEWSBLUR.reader.layout.rightLayout.toggle('south')

You can put that in Custom JS (premium only).
