Yup - I switched a while back and it improves things a lot - although it is still out by a bit. > It is not easy to do rectangular alignment on the surface of a sphere which > is basically what you're asking for.

Disabling or warning the user in EPSG:4326 would seem a major improvement. It just worries me that at the moment the tool makes data less accurate in the default projection - catching out new people and those least likely to realise there is an issue. I'm assuming from this that the new code from Harald doesn't resolve this? As I said not actually read it to check...
