pkg review help needed

Here's a few packages submitted recently that still need some reviewers:

Review Request: kf5-purpose - Framework for providing abstractions to get the developer's purposes fulfilled https://bugzilla.redhat.com/1266939

Dependency needed for newer kf5-based kamoso releases

Review Request: plasma-user-manager - Manage the users of your system https://bugzilla.redhat.com/1289738

Last plasma5 component not in distro yet

Review Request: marble-widget - Marble Widget Library for Qt4 https://bugzilla.redhat.com/1294211

For compatibiliy since latest marble-15.12.x releases drop Qt4 support. Needed by (at least) digikam/libkgeomap.

I'll be happy to swap reviews, if that will help getting things moving. Thanks in advance.
