Expand toolbar button is wrong

[Alfonso Martínez de Lizarrondo]

With an open toolbar the "collapse toolbar" button is an upwards-facing arrow. That's fine.

When the toolbar collapses it changes to a left-facing arrow, but it should be a down-facing arrow as that's the direction of the movement that will happen when it's clicked.

Hmm... I guess it all depends how you see it :)

Personally to me this left-facing position is let's say less aggressive then down-facing showing up right after up-facing arrow. I've also got use to it.

Anyway I'm confirming this. I wonder what others will say:)
