The documentation isn't very good (it's unclear which version) and I ended up having to install the local version on my Mac and manually copy/past the pages I wanted because the copy notebook dialog didn't work with notebooks that have many pages. The worst part is not being able to access the raw data and simply copy that from one place to another.
I've switched to markdown files on Sublime with the Markdown Editing package for now, because they are easier to read and edit, portable and I can convert my notes to wiki pages, blog posts or documentation very easily. I'm still not 100% happy because of the different flavours and how pandoc converts files differently sometimes (especially lists).
My goal for now is to have a simple way to record (the files) and manage (the folders) notes, collaborate (I currently use gitlab repositories) and potentially use them later, e.g. by copying relevant parts to make posts, documentation etc, or by writing a script that finds relationships based on the content (something I've been thinking about for links I save in Safari or Firefox too - a script that scrapes the pages and builds a tree to organize links automatically).
Maybe a tool that could navigate the files, extract headlines and content to figure out relationships out of the files would be ideal to help me compose new documents and posts.
1. Uncertainty about data export. I don't want to be stuck depending on a third-party proprietary solution for something so important to me. (That said, Microsoft is typically quite good about supporting products for a long time)
2. I actually find Windows unpleasant to use, and much prefer linux. (Arch linux + i3/KDE happens to be my preferred setup).
