Comment 7 for bug 881472

The problem with the arrows is that unico doesn't offer really appealing styles for them (since Ubuntu is using the overlay-scrollbars by default, scrollbars aren't really used there anymore and since Ubuntu employed the former murrine-now-unico-dev I don't see them focussing on that area in the near future). That is the main reason why I decided to drop them, and I assume that other theme designers did the same for similar reasons.
