I’ve no problem with using LibreOffice for most of my document needs, but i haven’t found a good substitute for microsoft’s OneNote yet. I mainly use it to plan my RPG games and it helps a lot. What alternatives are there for organizing notes on linux, with similar features to those that OneNote provides?
Rnote is currently the best for handwritten notes in my opinion, but its organization is minimal. I have never found a 1:1 replacement for OneNote, but luckily I no longer need it desperately like I did a decade ago.
