wouldn't it be better if programme's can halt shutdown to let user save documents

[Kristof Vansant <de_lupus pandora be>]

Wouldn't it be better if programme's can halt shutdown to let user save
documents. Or tell the apps it is shuttingdown so they can save the
current work temperary so the next time you boot you can reopen your
last work. Or does this exist and is the problem in the apps?
