For someone that makes a lot of notes that include pictures and screenshots it would be very important to have control over the image files I create. As far as I understand, by now there is no way to export a knowledge base with the image files included, only the links to the images. This would be with a sync KB, but as far as I know this does also not work with a local KB.
It is clear to me that the files woul be much bigger and would make the export more complicated, but for some of us this is essential. If I ever want to change my learning system or change my workflow I need to have access to all my data I have created up until now.
