eg if you have a project opened and you are looking at the history-subpanel and you want to add a new notice, then you want to assign the notice to a contact.
But if you start typing a name in the contact-field and hope for autocomplate, you have to know the first_name of your contact. If you just know the last_name (=typical in Germany), then the autocompletion don´t find the contact.
So how can I changed the autocompletion of contacts to look for the last_name?
Now you have a field “Contact” where you can start typing with auto-complete. If I know the first Name of a contact, I can find the person. If I just now the last name, I can´t use the comfortable auto-complate function.
