 # BUGS
 
-- retornar None quando nao ha alteracoes relativamente à última vez.
-ou usar push (websockets?)
-- quando scale_max não é 20, as cores das barras continuam a reflectir a escala 0,20
+- review does not show question refs when commandline --show-ref is used but not the test.yaml option.
+- em admin, quando scale_max não é 20, as cores das barras continuam a reflectir a escala 0,20. a tabela teste na DB não tem a escala desse teste.
 - CRITICAL se answer for `i<n` a revisão de provas mostra apenas i (interpreta `<` como tag?)
 - na pagina grade.html as barras estao normalizadas para os limites scale_min e max do teste actual e nao do realizado.
 - codigo `hello   world` nao esta a preservar o whitespace. O renderer de markdown gera a tag <code> que não preserva whitespace. Necessario adicionar <pre>.
