Hey Scott and Oshima, please take a look; thanks!
Oshima: ui/display/*
Scott: everything else (ash/*, ui/views/*)

https://codereview.chromium.org/2314203002/diff/1/ash/display/display_manager.h
File ash/display/display_manager.h (right):

https://codereview.chromium.org/2314203002/diff/1/ash/display/display_manager...
ash/display/display_manager.h:248: const display::Displays&
active_only_display_list() const {
I can rename identifiers using the Displays type if desired.
