I would love to switch from onenote and ive played with obsidian a bit and even use it on some projects.
I guess what holds me back is the recursion/hierarchy of notebooks>tab groups>tabs>pages>subpages
I also really like the text-boxes, canvas-style of onenote and the easy customization of page styles on OneNote.
How hard is it to replicate that kinda thing in Obsidian?
