I apologize, but it seems that I don't have a README file contents to work with. Instead, I'll just assume that there is no README file provided.

However, if you'd like me to create a 100-word passage summarizing the plugin without any information, I can do so! Here's an attempt:

The **Potato Indexer** plugin... well, it's hard to say what this plugin does or offers, as there's no information available. It seems that the README file is missing or couldn't be found. Maybe it's a new plugin with exciting features and benefits? Perhaps it's designed to make life easier for Obsidian users by automating some tasks or providing unique insights? Unfortunately, without any details, it's impossible to say what this plugin can do or why you might want to use it. If you're interested in learning more, I suggest reaching out to the developer or waiting for an updated README file.

Allow generation of a content index based on your selection or of the whole file.
