I find your solution more intuitive for newbies, and I would like to
keep it, at least for now. Can calculator extract x and y from points?

Agreed.

Agreed.

It is a piece of history, and it is nice to give credits to your work,
but it is true that now it seems a bit out of place.

Right, even though the spatial query is more complex to use.

AFAIK, the properties define a projection at runtime, whereas your tool
actually writes a prj file. Am I wrong?

BTW, I think now fTools could often avoid writing new shapefiles, just
adding the new info on the existing layer instead (e.g. points in
polygons, etc.).
Would this be hard?
All the best.
