 ## GENERAL
 
-    * trim joblog > (say) 100 ...  [DONE]
-        * then click for rest
-
     * refimgs need to be done via job_mgr:
         - have local FS chooser of ref img, do html file upload to b/e -> job mgr -> save it to reference_images/<p.tag>/<ref-img-fname>
         - remove refimg menu from top-level -> sub of Person (to view/mangage?)
