Let me say that this implementation is amazing. All that matters is automating work to be able to dedicate more fully to the knowledge itself, and with this you achieved it. I have tested the plugin on a ~33 Gb vault with ~20,000 folders (at least one note inside each folder, also images, videos, pdfs, 3d models in OBJ, etc.) and it runs great. The plugin was able to generate all the indexes, and it structured the Graph View quite well.
On the other hand, there is a warning: it is highly complex to configure the plugin to create indexes in certain folders and to exclude other folders. That is not working well at all. It’s not clear how the file paths should be placed, I tried many different combinations and none worked. When trying to delete the indexes, they are generated again. If you want a plugin that creates indexes on certain folders and not on others, then this alternative is still raw and needs participants to improve it. Also, it’s not clear how to implement a template over the indexes (e.g., for tags) if you don’t use the ‘templater’ plugin and you are using only the ‘templates’ core plugin. I wish I knew how to program, I would lend you a hand without hesitation. Excellent work!
