Hi Kat, I've used Ulysses, too, it's a great program! When it came to my creative writing projects, I preferred Ulysses to Scrivener, for sure.
I hope you'll enjoy Obsidian, let me know if you find another use for it or any helpful tips / tricks. I'm still playing around with the program, I really want it to become my go-to note-taking app. I love the idea of capturing everything in one place.
Thanks so much for reading and commenting! :)
