I feel like there is a need for a new paradigm on navigating code; and reference documentation for that matter.

I like how https://gwern.net and https://en.wikipedia.org allow you to hover over terms and show you a quick glance of a term you might not know, and then you can fan out to create an understanding for the basis needed to understand the material in front of you. I feel like some sort of windowing system where I can pin and move references around and then kinda have the llm explain or reference things might be of use to me, as in help me navigate the unknown. Is there a "study companion" application of the sort?

I find that this is easier to do with a language like Java than say Python, I need as much information as I can in order to understand the decisions that led to the current implementation.

Sometimes when I want to change some piece of legacy code, I need to know the rationale behind the code written here, although keeping the interfaces the same and changing the implementation allows me to go quite far.
