Ok. It took some time to figure out how it works. Actually you have to left click on a field in a column and not on a column name as i thought at first. I see what your patch is changing, but i think this could be confusing for some users without any explanation. Maybe the should be a text above the search results. Something like that: “To add a contact right click on a search result and select Add as a contact. Left click on a field to use it for a nickname in Add Contact dialog”.
