I would suggest ability to bulk edit organisation fields, when you are in list deal view.

Today, my use case was: export all contacts, that are under organisations, which have deals in these stages of pipeline

Since there was no possibility of bulk editing, first I created custom field for deals, did filtering and bulk edited them with "key" value. Then I went to organisation, filtered organisations, which have deals with this "key" value in custom field and bulk edited them again with custom field , created on level of organisation. Finally, I went to person list and filtered all people, which has organisation, that has this "key" value in custom field. These went to export.
