Comment 4 for bug 1171477

Personally I think either of these is fine. There are also plenty of hits for "screen estate" on Google; I skim-read a couple of them and at least some of them appear to be written by people with an otherwise good command of English. I don't think we need to change this for 13.04.

However, perhaps "Preserve screen space" would be less contentious and clearer; we could switch to that for a future release.
