furo VS sphinx-immaterial

Sphinx has more and in my opinion better themes (especially the popular Furo them). I also think it's better for handling large and complex sites. It's way more extensible. That there are far more Sphinx users means that you're more likely to have community support if/when you run into issues.

My company uses sphinx, in particular the furo theme: https://github.com/pradyunsg/furo. I'd like to use something like this to start documenting our Rust repositories. Is this possible on stable?

On another note, what did you dislike in Sphinx ? I found it pretty easy to work with until now and there are quite nice themes, like Furo (https://github.com/pradyunsg/furo), which is actually pretty similar to your current docs theme. I used it recently for one of my projects (see https://francois-rozet.github.io/piqa/piqa.psnr.html).

reminds me a lot of Furo which is used by big names such as urllib3, pip, attrs, psycopg3, black

This theme was created by one of the maintainers of pip, which is where I first saw it (https://pip.pypa.io/en/stable/). Here are some of the things I like about it:

- Well-chosen, proportionate font sizes and spacing.

- Table of contents sidebars for both the current page and the whole documentation site.

- Fully responsive: sidebars disappear in narrow windows or small screens, but can still be popped out.

- Clean color scheme with good contrast, and full support for dark mode (see screenshot at https://github.com/pradyunsg/furo/blob/main/README.md).

In case its useful, the sphinx-immaterial theme claims to support similar searching functionality.
