The Dataview plugin is the most critical one. You can create queries with your metdata. If that sounds like nonsense to you I highly encourage you to check it out because it’s super cool. I think of my Obsidian vault as my second brain.

Some cool examples here that you can click through. Also note that because the obsidian pages are in markdown format you can use the Jekyll engine to directly turn them into web pages (this is how GitHub Pages works)
