@vickysteeves @remram44 I've never found a true onenote alternative. I ended up using emacs' org-mode for most things. Xournal for hand writing, but honestly didn't productive use it. There are mods you can make to org-mode that will display images inline..
I ended up just taking photos of my notes. Now, with touchscreens, I'd probably draw in krita and append/display in org-mode mode.
