I had to think of Obsidian as well. Even if it's not open source, the devs are very transparent about their software. And categories is what you could create via meta-data and use a plugin to easily find them. Folders you can create as well.

It's the quenchiest!
Curious how that'll work out. I like Avatar. I like Magic. I just can't really think of this combo as they're 2 totally different 'worlds' to me.
