I often make documents which I quickly need to save. In MS Word it then simply gives the first few words as filename option which you can then of course change as you like, but it is at least something.

If I save something in OOo it doesn't give anything. So if I need to save something I cannot simply click save > save. I need to think of a name. And although that is not a hard thing, if I'm in the rush of work and I got a document which simply should have the same title as the first few words in the document (eg. "friday-list for Bob") I want it to go quick.

It is a small thing, but it would make my life again a little bit easier. :-)
