I guess this extension makes it easier to get an overview of the directory structure, but that's something I rarely need.
I'm sceptical of browser plugins in general. There are so many browser plugins that change under the hood and do malicious things. It would be easy for the author of this plugin to scrape all your source code and phone it home.
I understand the concern. This extension is open-source/MIT [1], hope that brings a little peace of mind. If not, you can just pack the extension from its source instead of installing from Chrome Store.
