No it can't, and perimeter calculation seems to be an issue as well.
Ok, well then I might change this to be a wrapper around the field
calculator, that way it will be intuitive for beginners, and still
have the added functionality of x and y values and perimeter.

This one I will not be sad to see gone from fTools! Good riddance ;-)

I'll just move all the 'credit' related info to where it belongs in
the main QGIS about dialog I think. I don't like how it looks the way
it is now, and for the most part, fTools is now referred to as the
Vector menu, so beginners probably don't even know what fTools is....

Hmm, yes I tested it just now. It is a bit more complicated, but not
overly so... thoughts from others?

True, it does write the prj file, but I'm talking about the new
feature from recent builds... the tool doesn't have an icon yet... am
I crazy?

Not overly hard no, and there are really only a few tools that this
would apply to.

One thing I'd really like to do is add the capability to output other
formats besides shapefiles (I'm not a big shapefile fan these days,
field name limitations are a hassle). I might try move over the
geometry and geoprocessing tools first, as they seem to be the most
frequently used tools.
