Using the toggle functionality I defined earlier, create a toggle
eshell setup

+to mind). However, I'd argue that eshell's greatest ability comes from
+it's separation (or perhaps better phrased, *integration*) of two
+'parsers': the Lisp parser and the Shell parser. With these parsers

-However, the Eshell is still a useful tool even if you don't use it
-for classical shell tasks. As it is integrated with Emacs, it actually
-has two language parsers: one for standard shell scripting [echo
-"Hello, world"] and one for Emacs lisp [(message "Hello,
-world!")]. This means that eshell is essentially just a REPL for Emacs
-lisp with extra shell capabilities. You can use programs defined in
-any language (as long as it's in path and executable) and also run
-lisp functions. This allows for mix-and-match capabilities when
-needed, so cognitive load decreases as you can rely on either parsers
-when necessary.

 * Window management
 Window management is really important. I find the default window
