Rated 4 out of 5 stars

I am looking for a way to know in which subadressbook my contacts already are.
With this add-on, it is possible to compare contacts by using two tabs, but it is a lengthy and complicated task.
I would like to have an add-on that for exemple add a context menu to a specific contact allowing to select / unselect from a list to which subaddressbooks this contact belong.
Is that possible ?

This review is for a previous version of the add-on (1.3.2).
