Thanks for mentioning markor, I was searching for something similar!
How do you sync your notebook between your phone and your computer, if you don't mind me asking?
Back when I was searching for a good note-taking system, each and everyone of them had one feature that I wanted that was missing. Zim Wiki was the first system I decided to stick with, and after 4+ years I never gravely missed anything. However, if you don't like organizing your stuff hierarchically, your experience might differ. Also, I kinda dig the desktop-centric approach. It feels more like a real tool than just some kind of "app".
Because it's written in python it is comparatively easy to extend and through its integrated web server you can serve up your notes with a custom design in no time.
The current workaround for this would be to use an app like IPWebcam and route the network traffic over USB with adb, then ffmpeg it into v4l2loopback on your computer.
I have been using an old smartphone as webcam for quite some time now, and I got to say it works quite well. The only problem is the power supply, because video recording draws a lot of power it drains the battery even when it's plugged in.
Of course, an out of the box solution with UVC would be much nicer!
