  wait_until { has_link?("Edit note") } #<-- This is BAD, esp. when the note to be added is yet another row in a table having "Edit note" link for every corresponding row in that table
  #wait_until { has_text?(notes) } #<-- This is GOOD practice that enables test stability and hence faith in test results
