Recently I started reading Mark Jones' Knowing Christ from Banner of Truth on the Kindle format on my iPad, and using Logos to look up for the scripture reference used in the books for notes, and this idea kick in....
If Logos can allow user to open and read epub or mobi based eBooks within the application it self, we will be possible to highlight and make notes with other additional tools within Logos, and the best part is if there are scripture references in the book (which is every paragraph in Knowing Christ), we can just hover or click on it and it will jump to the text directly....
I think any Puritans readers will be benefit if Logos implement this feature.
