 ## GENERAL
-    * faces less than 43 pixels are all false matches, so lets add this to settings and "auto-ignore" all faces < 43 pixels
-
-    * [DONE] order/ find face with largest size and at least show that as unmatched
-        - could also try to check it vs. other faces, if it matches more than say 10? we offer it up as a required ref img, then cut that face (with margin) out and use it is a new ref image / person
-        * on viewer: allow face to be used to create person, add to existing person, and allow 'ignore', mark as 'not a face', etc. -> all into DB
-            - so need face 'treatment' -> could be matched via face_refimg_link, but also could be 'ignore' or 'not a face', in each case we could exclude those faces from
-            matching for the future, and reporting on matches, etc.
-            - context-menu with rects on a canvas

-            - also allow joblog search from the viewer for that file...
+    * on viewer: 
+        - allow face to be used to create person, add to existing person, and allow 'ignore', mark as 'not a face', etc
+            -> ignore/not a face/too young --> all need to go into DB so we can remember the 'override' when we re-ai-match
+        - allow joblog search from the viewer for that file...
 
     * should allow right-click from View menu (particularly useful on search) to show other files around this one by date (maybe that folder or something?)
