Comment 3 for bug 287913

> Envelope and Perspective aren't as user friendly.

If you are talking about the extensions that is probably correct, specially if you work with multiple objects and don't want destructive changes. But path effects are more flexible in this sense so I invite you to try a newer release: http://sourceforge.net/projects/inkscape/files/

The problem is that in the following release (0.47) only envelope effect is activated and it doesn't seems to work with groups.

> Plus those python extensions don't seem to be working under Snow Leopard.

We know there are a number of problems with extensions on OSX for 0.46, however we're talking about path effects here (Path menu-> Path effect editor...), not the extensions.
