You may have been making good use of our Leads/Sales pipeline and have created Leads linked to your contacts.
Now you need a quick way to connect back to the contact record from your Leads in your pipeline view:
A: Hover over your Lead in the pipeline and you will see a pop up message just to the right of your Lead, within which is a link to click through to your Contact. So just drag across and click through to the Contact record.
Hint:
If you are making good use of the Tasks linked with Leads then for your Task email alerts it is a good idea to put the Contact/Org name into your title.
