Har nå mulighet for default-valg i confirm (default-en vises med stor bokstav, som i '(Y/n)', og velges hvis man skriver en tom linje), og confirm leser input på samme måte som alt annet (via Menu.input_str). Har laget en funksjon safe_str som prøver å gjøre om et vilkårlig objekt til noe Python kan printe uten å bli sur. Tok i bruk denne i raw_input-kallet i Menu.input_str (det viser seg at raw_input blir muggen hvis den får et unicode-objekt som inneholder ikke-ASCII-tegn).
