Done.

can't pass a non-const reference in Chrome

I think it's convention in the current app list models to typedef a collection
of item-models (see e.g. app_list::SearchResult, app_list::AppListModel). You
could do (in AppListMenu), 

typedef std::vector<ui::AvatarMenuItemModel*> AvatarMenuModel;

referred to as AppListMenu::AvatarMenuModel

But there might be a better name for it (just AvatarModel, or AvatarsModel, or
ProfilesModel..). A typedef in AppListModel might make more sense, too (just
noticed it's used there..)

[calamity, 2013/08/01 08:35:45]

Done.

[calamity, 2013/08/01 08:35:45]

Done.
