This program rocks for any sort of organization.
Markdown files in folders, with all sorts of plugins for tweaking it to your use case.
But beware, Obsidian is full of rabbit holes. Don’t get distracted by shiny plugins that you don’t actually need.
It’s an amazing tool.
For your comics list, I’d suggest Dataview, quickadd, and templater plugins. With those three you could easily make a database with an entry mask, that automatically sorts the files into folders and sets metadata based on the mask input, and dynamically creates various tables for reference.
Folder notes could be useful too, depending how you want to set it up, and how detailed you want to have your tables.
Whatever you decide on, good luck. :)
