Well, the notes section of TreeDBNotes works like Word, with similar options. So I copy-pasted everything from the manuals into a tree database, including images and links. I had to create tables in TreeDBNotes though and copy-paste each entry. The most tedious part is done since as you can see I've entered everything. So updating the file is rather easy. Like for the INI section which was update a few days ago, I just added another line at the bottom of the cell of Boost in the table and copy-pasted the new one CueMark, which took me about 5 seconds.
It's possible the app needs admin right in order to create and modify the ini file that is created after you open the ebook the first time.
