If you have enough RAM or buffy workstation and you can install VirtualBox inside Windows and use the Marketplace based OneNote or install Office. I think, you do not need ```p3x-onenote``` at all.
For my workstation, with a 4.8Ghz CPU, 4 cores, 32 GB-ram, I use VirtualBox on Windows with Office Onenote (I use 6 GB RAM, 4 cores), but unfortunately my Laptop is old and has only 16GB RAM. Given, I develop a lot (NodeJs), I need the RAM, so for my Laptop, I use ```p3x-onenote``` and it's enough. Once the pages are loaded. It is fast, since it's own process without a browser and is in the tray, you don't have to re-load everything again. So it is very usable and after all pages are loaded, quick.
**You can try, you loose nothing.**
