Is there any way to sort "Faces" alphabetically in the new Photos App for OSX?
There's now a sort by name feature! In Photos version 1.2, you can go to the Faces view and then do View > Sort > Keep Sorted By Name. Ridiculously, this is apparently turned off by default if you upgraded from a previous version.

Anyway, this will make my use of Photos way way easier. (I have 1400+ faces.)
