 # 4 TEST everything (don't forget keybindings,e.g. delete)
-#   -- go into viewer code from a files_rbp - had red bin, bot green on viewer.
-#
-# consider this:
-   $('#viewer_bin use').attr('fill', 'var(--bs-success)'); $('#viewer_del').removeClass('btn-outline-danger').addClass('btn-outline-success')
-   $('#viewer_bin').hover(
-  function() {
-    $('use', this).attr('fill', 'white');
-  },
-  function() {
-    $('use', this).attr('fill', 'var(--bs-success)');
-  }
-);
+# - from viewer, if I del, then it stays on this view, should not (OR at least)
 #
 # 5 think I killed pa_job_manager without passing an eid to a transform job, shouldn't crash
 #    SHOULD JUST get AI to help clean-up and write defensive code here...
