No matter in which list tab you are the deletion of a data record is always a permanent deletion of the data record from your database! The active list tab is always the basis for further actions from the Actions menu (e.g. the mass update) or from the Actions bar.
With list tabs, you always have frequently used filters or a worklist of contacts at your fingertips. For example, the worklist for phone calls.
You can configure the view and sorting of the list tabs independently. The content can also be configured, but the 2 standard list tabs “Active contacts” and “All contacts” can only be changed to a limited extent.
For list tabs that are based on a worklist, this is indicated in the tab by a symbol in front of the name. In addition, the name of the underlying worklist is displayed in the navigation bar at the bottom.
If you have created more list tabs than there is space for in the tab bar, the arrow symbol appears, through which you can select and configure the other tabs. You can also change the order using the edit dropdown in the individual tabs.
Additional worklists and filters are selectable. You can further limit the listed contacts in all tabs using a contact filter . You can select a worklist only for the tabs that are based on a filter.
