KDE CDEmu Manager is a simple Qt5/Kf5 frontend for CDEmu.

It provides a little manager window that gives you an overview
of your virtual drives and allows you to mount and unmount images.
It also includes a KDE service menu for mounting images directly
from Dolphin/Konqueror (which is what most people will want to use).
Images can be unmounted like any other media through Dolphin or the
Device Notifier plasmoid.
