What I want from a note taking app:
* Takes pages from my browser
* Uses github to sync across platforms
* Has offline reading on mobile
* Tagging and a todo list for triaging notes.
Haven't found one yet.
Here is a way to capture pages from the browser in Obsidian https://stephanango.com/obsidian-web-clipper
https://github.com/denolehov/obsidian-git will help you sync across platforms
Obsidian has all files locally so can be read offline
I use a mix of tagging and two plugins (dataview and tasks) to accomplish the last one.
