It's possible to look after a contact over all lists?

If you want to open the profile of a contact, but you don't know in which list you can find him just use the global search function.

You can open it with the lens symbol.

Enter in the search field the address you're looking for. The result shows all lists and with a klick you can open the profile in the chosen list. The same function works for campaign names. If you search for a campaign it shows you the name, type and status of a campaign.
