Batch modification of multiple contacts
Feature Request:
Please add a functionality for batch modification of multiple contacts. Currently I'm doing that for Google Contacts via the Google web interface.
Use case: Select multiple contacts and show a batch modification dialog similar to the simple modification dialog. Shared data should be displayed, different data should be hidden. Any changed edit field like "Company:" or "Categories:" should be applied to all the selected contacts.
Special case with categories: All shared categories among the selected contacts should be displayed as "✓" (selected), categories without any reference should not be selected, and categories that only some of the contacts sharing should be selected with "-".
Purpose: This is highly useful for adding a list of contacts to a category or company without copy/paste between the contacts.
