Code review comment for lp:~dandrader/unity/lp940612

You don't need this check in the method any more, because it is caught by rbegin() == rend().

171 + if (client_list_stacking.empty())
172 + return nullptr;

Once you push, you don't need to resubmit. Launchpad will just update the diff.

Do we have any tests for this?

Is there any way to "fake" utouch events?
