An idea on how to turn Autosave off

hi

1. if run software designed snow leopard on lion machine software doesn't autosave.

2. seems fact apple never let user able toggle autosave on/off.

when developers update software lion there reason them not make autosave can turn off in particular app? autosave must feature app developer deliberatly puts software? can't make user can toggle on/off?

know it's bit tedious user have turn off in every single application @ least provides way apple has decided imac has work 27" iphone
