The MyScript is the Nebo App. Compare Nebo on Android and iOS tablets that have a pen/stylus/pencil digitizer.

It would be nice to be able to use a BT KB in the Notebooks (you can't) like you can in any window that uses the touch keyboard.

It would be nice to have handwriting recognition in the annotation window (I think hard for Kobo to integrate).

PDFs don't always have a text layer. It's a multilayer container and each layer can be text (often similar to postscript), lossless bit maps, vector art or whatever. It's trivial to add an extra image layer if there is no DRM. Hence PDFs work differently. A PDF is really a method of WYSIWG instructions/data for paper. It doesn't need sequential content. A real ebook is sequential HTML tags on the content text and option images with CSS styles for the tags. So creating a separate annotation file with highlighted source, position and user added text is trivial.

A PDF might not actually have text, and it's often not sequential, so a PDF can only easily be annotated by adding the annotation as a layer to the document.

Inherently word highlighting to select text for the annotation file is easy for epub. It's easier to treat a PDF as an image even if it has text.

All the things you suggest would be really hard for Kobo, who have the source. Also they might not have the source or much documentation on Nebo (the Notebooks) as it's a bought in app.

Also there is NO import to the Nebo based Notebooks other than copying Nebo files between ereaders (you also need an entry in Kobo ereader.conf).
Copy/paste even between notebooks doesn't seem to work and I only got it to append paste, not insert paste in a notebook.
Basic and Advanced Notebooks seem unrelated.


There is a Nebo viewer for Mac and maybe Windows. I suspect the Nebo files on the Sage/Elipsa will work with that and with the iOS and Android Nebo.

Short answer:
I doubt you can do more than implement a menu to import/export Nebo files via WiFi to iOS/Android Nebo.
