The app's main screen

The app is split into three areas. The top bar allows you to select the Kindle's™ drive. It also allows you to undo the changes made in this session, perform a "1-touch-sync", filter what's displayed in the panes, set up the KCM and finally eject and/or commit changes to your device.

Renaming a collection

An existing collection can be renamed. You're not limited to just using English characters here. Your collection can contain any characters you can type or can copy and paste.
