Computational Inefficiencies

I like the theme and won't change my 5 star review. However, long chats (often using thinking mode) load much slower than without the extension. For example, enabling the theme would take a page of 5 thinking mode messages ~10-15 seconds to load (sometimes crashing the page), while disabling the theme takes 2-3.
