As promised here is the uninstall routine for the qtscript and tweaks plugin.
Just attach the reader to your PC and extract the file to the .kobo directory. Unplug the reader and it should install automatically.
This update only replaces the original plugin files with empty files.
Tomorrow I'm providing a new version with 'voom's icons as well as a simple firmware version check. In case the firmware gets upgraded the plugin won't start.
What I'm trying now is to hide the complete Menu and replace it with custom shortcut icons for library .....
