 * Shell
 ** Add faces instead of reusing font-lock-{comment,string}.
-** Understand ~autocd~ and ~cd !$~.
+** Improve directory tracking.
+Ensure ~default-directory~ remains consistent with the shell's current
+working directory.  Some things ~shell-mode~ does not handle:
+
+- ~autocd~ (there's ~shell-has-auto-cd~, but it does not track whether
+  ~autocd~ is *actually* set)
+- ~cd !$~
+- ~ssh~
+- Docker containers
+
+Some solutions:
+- Emacs 28's ~comint-osc-process-output~
+  - requires configuring the prompt
+  - does not handle SSH (yet)
+  - relies on OSC 7, which is [[https://gitlab.freedesktop.org/terminal-wg/specifications/-/issues/20][not standard yet]]
+- running this clumsy thing after every command:
+  #+begin_src sh
+  (file-truename
+   (format "/proc/%d/cwd"
+           (process-id (get-buffer-process (current-buffer)))))
+  #+end_src
+
 ** Use Bash completions.
 E.g. in most terminals, typing ~ls TAB~ in a folder with a single file
 expands to ~ls that-file~.
