I use an editor-construction kit named "Emacs" to build my own Editor, and IDE, and git porcelain, and organizer, and wiki. And many things more.
IDE with e.g. LSP integration, rustix and many other programmer-related modes and enhancements like tree-sitter. Git porcelain with magit. Organizer with Org-Mode. Wiki with denote.
The only thing I miss in emacs is concurrency/multi-threading. Apart from that, it's a complete software for me. Anyone can build it to anyone's liking.
Emacs has primitive concurrency (see Chapter 40, Threads in the Elisp manual), and because it's a Lisp, having nice concurrency is just a matter of programming.
