Hi Michaël,
I think I give a look at Query builder source code before writing a FR
during these holidays. It would be a good developing exercise. If you
agree Michael.
I want also to check the possibility to add logical operators like AND NOT
OR but probabily this requires other stuff (geotools?). I will see also
Kosmo solutions on their Query Builder.
Adding "Complements results" and "Zoom to selected" to other tools seems
interesting (like in Geometry function toiol): the idea to homologate all
the options in all query/tolological/etc tools (whenever it is possible)
is not bad.
