Yes and I love it.

I linked Obsidian with ToDo-ist for portfolio work and it’s helped keep me on track.

Here is info on that if you’re interested: https://github.com/jamiebrynes7/obsidian-todoist-plugin

There is a way to make a To-Do system in obsidian but it required too much micromanaging for my ADHD brain, so I went with the todoist option for now.

I’m still learning all the Markdown stuff. Since I work in art/illustration I use obsidian to catalogue all my references, make daily journals for my progress, and collect code snippets for python/html/css for when I need that stuff later. When I’m less busy I’m going to include all my art books in an obsidian reference library.
