1. Allowing multiple field selection for grouping
2. Keeping attributes of first feature when grouping

I will accept this criteria, obviously, if it's the preferred solution for
the mosts.
I just want to report that many users (partecipants to courses or
customers) say they find having the "first feature value" misleading.
I agree with them. I would set the field values only for the grouping
fields, having the same value within the group, and set null for the other

The problem raises during a long workflow. At some point you obtain a
dataset with unconsisten field values, and it's not always obvious to know
when and.which field value was set miningless.
