I am missing a field within the Proton Contact: Middle name.
Here in the Netherlands, it is common for people to have "de" "van der" etc. before their last name.
And; when I sort my contact on 'lastname' I don't want to add "de" or "van der" to the last name field - because then, they are sorted wrong.
So, the request is to add an additional field "middle name" to the contact.
Which is show between first name and last name of the contacts.
