For the purposes of Lisps there's Emacs with Paredit (or other editor with Paredit, there are versions for most of them I think), for the purpose of notes there's Emacs with Org-mode. For the purpose of Java w.r.t. refactoring and navigation there's Intellij, Eclipse etc. For the purtpose of Python w.r.t. refactoring and navigation there's Pycharm. And so on. I use a combination of (1) Emacs & Org-mode for structured editing of notes and prose, and (2) Whatever IDE is most suited for the language I work in.
