 ## GENERAL
 
+    * make code use FLASK_ENV var to use a pa-devdb equiv 
+    * create a new table file_face_refimg_link:
+        file_id, face_enc, ref_img (can be null)
+    * need AI code to:
+        scan for unknown faces, instead of storing array of all faces in FILE->FACES use table above one row per FILE & FACE with refimg_link as null to start
+    * when we do ai matching, we find all refimg is null (for a specific file) and match that
+    * need pa_job_mgr AI jobs to have low-level functions:
+        FindUnknownFacesInFile()
+        MatchRefImgWithUnknownFace()
+        Then create wrapper funcs:
+            MatchPersonWithFile()
+                for each ref img for person
+                    MatchRefImgWithUnknownFace()
+
+            MatchPersonInDir()
+                for each file in Dir:
+                    MatchPersonWithFile()
+
+    * then in UI:
+        allow right-click folders in folder view (at least for AI scan) for all files in Dir
+        allow right-click AI
+            for all persons
+            for individuals
+        (and can be on an individual file or an individual dir, or selected files / selected dir)
+         
     * fix up logging in general
     * comment your code
     * more OO goodness :)
