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?
How do you sync between devices? Dropbox or Syncthing?
I find myself favoring self-hosted webapps over local running apps. It eliminates the "no client for X platform" problem while also providing syncing across devices.
Amazing application. Comparable and better than everything I've seen on hacker news over the years.
My only complaint is no mobile client, though markor can generate a Zim-Wiki file.
