Imported images that are not used anymore by quick-memo should be deleted to clear some space on the device.
Actually ContentStore does not provide a function to do this action, and 'org.nemomobile.folderlistmodel' is not available for third-part application, so a C++ plugin seems to be required.

The code for the plugin is already written (I use it for other project that are still not released publicly), but further information on ContentHub design are definitely required.

The milestone for this bug should be the version 0.4 of quick-memo, when the project should be re-written using "App with QML Extension library" (provided by Ubuntu SDK) as template.
