Updated the first post for more info.
In a nutshell, I just release the
v2 of the KoHighlights utility.
Its a different application, written from scratch using Pyside (Qt for Python) that has the same name with the old one because it has the same goal of reading and converting the KoReader's highlights to text.
But it has a nicer interface and its ready to also import the notes that the great Koreader developers will implement on day :-p
