@sgul Dataview, quite an advanced plugin. If you have some basic SQL commands knowledge it might feel familiar.
But if you're still new to Obsidian.. maybe first get the basic knowledge down pat first.
Until you decide you'd rather want to make a movie database!
Or books database!
Or whatever collection you have!
Then Dataview will come to the rescue. ;)
@sgul I'd suggest to already get familiar with YAML (front matter) and to categorize/standardize notes that way. It'll help out a lot in the long run when you go use Dataview. :)
