In Ideas > People > Contacts: Add filters and ability to add columns Merged

What is the challenge?

I cannot validate membership of portals in Contacts page.

What is the impact?

It is difficult to see data overall and edit as needed.

Describe your idea

While I can look at a portal to determine what users have access, I would like to be able to ensure that access shows in the contact list. Also, I will be able to see overall what contacts have access to which portals without having to click on each contact.
If similar functionality was given to the Contacts view as other list, I could add columns or filter to see this data easily.
If this functionality already exists in Lists, it would be good to have a link to surface the information there so I can understand WHERE to view and manipulate the data to answer questions that come up about user participation.
