+find a way to get unique ids (are ids mandatory in preferences anyway ?)

In the preferences, those 'id' attributes aren't really Id's, unlike in SVG itself.

Basically id attributes in prefs are not required to be unique in the whole document, but to be able to access things they probably need to be unique within a given parent.
