+;;; Commentary:
+
+;; Emacs IPython Notebook (EIN), despite its name, is a jupyter client for all
+;; languages.  It does not work under non-WSL Windows environments.
+;;
+;; As of 2023, EIN has been sunset for a number of years having been
+;; unable to keep up with jupyter's web-first ecosystem.  Even during
+;; its heyday EIN never fully reconciled emac's monolithic buffer
+;; architecture to the notebook's by-cell discretization, leaving
+;; gaping functional holes like crippled undo.
+;;
+;; Certainly in 2012 when jupyter was much smaller, an emacs client
+;; made perfect sense.  With many years of hindsight, it's now clear
+;; the json-driven, git-averse notebook format is anathema to emacs's
+;; plain text ethos.
+
+;;; Code:
+
+(when (boundp 'mouse-buffer-menu-mode-groups)
+  (add-to-list 'mouse-buffer-menu-mode-groups
+               '("^ein:" . "ein")))
+
+(provide 'ein)
