**Problem**: Contacts can only be restored temporarily. There is no way of restoring them afterwards. (heuristic no. 9)
**How to reproduce**:
Choose a contact in the inbox
Click "delete"
**Actual Outcome**:
the contact is deleted directly.
Restoring the contact is not possible except for the approx. 5 seconds immediately after deletion via the "Undo" button on the lower right side of the window.
**Expected Outcome**:
When deleting contacts, they are moved to the trash. There, you have the possibility to restore contacts or delete them finally by pressing the "delete" button.
