I saw a couple other older posts about this, but I recently began using Joplin for some notes (work, here, school). It is free, and has great folder organization and markdown support, dropbox integration as well. Just a quick shout out for anyone looking to stay organized starting out in 2020!
I really enjoy Joplin, but have moved to Notion for most of my note-taking purposes just due to the fact that you can do SO MUCH with it. That being said, I 100% support anyone using open source tools such as Joplin.
Looks great, thanks!
Have not had a chance to check out notion, but I will. Thanks.
