<p>Hi,</p>
<p>When I am extending an existing line with the vertex tool (by enabling the vertex tool and clicking on the small "plus" symbol), can I then still activate the "tracing" functionality to follow along other features?</p>
<p>If yes, I haven't found out how - any hints would be appreciated a lot!</p>
<p>Thanks,</p>
<p>Andreas</p>
