I turned my Obsidian vault into an computerized venture tracker with one free plugin
Building a large library of notes inside Obsidian is easy, but finding specific information across thousands of files makes it genuinely difficult over time. While it is great when you are a beginner, once you start spending twenty minutes looking for a single note, you see the issue. The Dataview community plugin is exactly what you need to turn your local file system into a searchable database.
