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 looked at Joplin and Obsidian for the kind of notetaking I do and settled on Obsidian. To be honest, both have more features than I use. I like Obsidian because it’s based on Markdown, so you’re not tied to some oddball file format. But you should try them out and see which one fits your work style.
