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?
I use and enjoy Joplin. It’s much less feature-rich than OneNote, but if you’re predominantly using it to make text-based notes it does that with aplomb. I enjoy the cloud syncing, which is very useful combined with the fact that there’s an Android app (so I can access my notes on the go).
