I second that. One of the biggest reasons we use Plesk is the email groups. Before Plesk we had CPanel. Doing an email group required making seperate forwarders with the same name for each person in the company (170+ people). This has the drawback of rogue forwarders being left after an employee is terminated. The groups made management very simple, delete the email address and all related group memberships are also deleted. Hope this feature is returning. I don't know of any other panels that have it but if we're stuck with a lack of features, better to use something that costs less.
