I think you have a few unnecessary headers here.

[msw, 2016/10/03 19:14:23]

Done; let me know if I missed any.

This and the class below could use a comment about when they are used (classic
ash vs. mash).

[msw, 2016/10/03 19:14:23]

Done.

Only create the one you need based on IsRunningInMash?

[msw, 2016/10/03 19:14:23]

Done.

+  SetTitle(window, l10n_util::GetStringUTF16(IDS_SETTINGS_TITLE));

[James Cook, 2016/10/01 00:16:21]

This function, and the ones below, need to be in a namespace property_util or
static class PropertyUtil. It's confusing having a bare function called
SetTitle().

[msw, 2016/10/03 19:14:23]

Done.

+  ui::Window* ui_window = aura::GetMusWindow(window);
+  DCHECK_EQ(chrome::IsRunningInMash(), !!ui_window);
+  if (ui_window)
+    ui_window_tracker_->Add(ui_window);
+  else
+    aura_window_tracker_->Add(window);
+}
