AFAIK -webkit-box is deprecated in favour of flex. I think we shouldn't use it
in completely new code. WDYT?

[yoshiki, 2014/01/24 15:34:19]

Done.

Can you please copy paste the scrollbar from Files app so it is consistent? On
the mocks it looks the same.

[yoshiki, 2014/01/24 15:34:19]

Scrollbar in Files.app doesn't work here for some reason (maybe due to
shadowdom?). I'll investigate farther, but let me keep it as is in this patch.

[mtomasz, 2014/01/27 01:09:24]

SGTM.

[mtomasz, 2014/01/23 08:05:09]

Is this needed?

[yoshiki, 2014/01/24 15:34:19]

Removed.
