Hi Jonathan,

Basically to reduce the file size (currently I'm working on a group project at uni and we have very limited space in our group directory).

I guess it dpends on your system and the relationship between the speed of the CPU and the speed of the drive.  I did some quick tests cating a file and runing  gunzip -c of the compressed version of the file.  In my case cattign took 0.046s and gunzipping took 0.065ms.  Not a huge difference.  I stronly suspect OpenOffice is slow for a whole set of other reasons.

I should also point out that I'm not trying to say that umbrello should (un)compress all files, only if it ends with gz.  This way, uses who have space problems can use less space and more cpu.  Users with plenty of space  can use more space and less cpu.

My goal at this stage is simple to get it onto the todo list as a "no harm done/may be usefull" feature enhancement.  If then after a while no-one get's to it, then I'll make the effort to create a patch (ahhhh, too many projects, to little time).  I just don't see the point of (or have the time to) creating a patch unless I know that that actual princicpal will be accepted.
