Missing the most important CRM feature

Hello,

First let me Thank You for providing this Great plugin for free!

The only feature missing from your CRM is the ability to record Opportunities and Leads as we record Clients and Companies and in my opinion this is the entire ideology behind CRMs.

For example, we are giving quotes and discussing new opportunities with existing clients most of the time. New opportunities are arising in a much bigger scale from existing clients instead of new ones.
The system needs to be able to record Opportunities and Leads independently and have the option to assign them to Contacts and/or Companies. We should be able to assign multiple Opportunities and Leads to each Client/Company.

Thanks again!
