Hey there. I just figured this out and it took more searching than I had expected. So I hope this post helps you, future searcher.
If you use the Daily Notes or Periodic Notes plugins for Obsidian, and you hate that it creates all of the files in one giant folder, you can clean it up by telling Obsidian to create intelligently nested folders by year, month, date or whatever else you’d like.
I love Obsidian. I'm writing this post in my main Obsidian vault right now, actually. You should check it out for yourself, but in brief, Obsidian is a very powerful notes management application with document linking, among a bunch of other great features.
I also love playing tabletop RPG games. My current favorite game is Quest, but I mostly play D&D 5th edition. Specifically, I mostly DM when I play, and I've constantly been searching for an actually good digital DMing setup.
It wasn't until after I had already begun building my own app specifically for DMing that I found Obsidian, which basically did everything I was planning to build. Though it does lack some of the features I wanted, but still, it was enough to make me stop what I was building and find a way to work with it. Let's run through my process and why Obsidian is so dang good for DMing.
I'll preface this by saying I mostly run custom campaigns in custom worlds, but I believe even without having a trove of your own custom written content, Obsidian proves useful.
