Congrats~pydata-sphinx-theme is becoming better and better.

Our Project MegEngine (A fast, scalable, and easy-to-use deep learning framework, with auto-differentiation) is using this theme now. [The Doc Site] Hope to be added to your user list.

As you can see, we add a simple version/language switcher. (MegEngine#1) Are you interested in this feature?

Very cool! Yep feel free to create a PR so we can add it to the list ✨

For the version switcher, that looks nice, thanks very much! There have been a few other discussions around the version switcher, want to discuss there? #23 is the main discussion, and there's one proposed implementation here #276
