Is Obsidian the Closest All in One App?

The obsidian app is the core plugins. Is it the community plugin? If that makes sense. The entire workspace drastically different, but the behind the scenes is still obsidian. And with the API it's going to get even closer. These are all videos I plan on putting on the YouTube channel and the way that I see the course and the YouTube channel is because this is what I struggle with in notion. So be prepared of lots of shorter video for people who don't want to spend like 51 hours learning how to do something.
