Emacs org-mode includes the function `org-latex-preview`, which provides image overlays for LaTeX formulas in the buffer. As it turns out, it mostly works in non-org-mode buffers. It does throw warnings. I have suppressed them with this little wrapper:

```
(defun tws-latex-preview (&optional ARG)
(interactive "P")
(let ((warning-minimum-level ':error))
(org-latex-preview ARG)))
```

Not rigorously tested, but seems to work for making pretty comments in my source code.

yesterday i discovered swagg.el, which wrangles swagger /openAPI specs in Emacs and interactively generates requests against them.

today i hacked up hag.el, which hijacks swagg.el to generate a full client library for a swagger API. (early days but the code is pretty clean, much more so (dont ask me why) than the common lisp openAPI clients i tried and cried with...)

As someone who went straight from command line Git to Magit, I'm just now learning the built in vc-* commands are pretty good, vc-region-history in particular which shows the commit history of a selected region is pretty killer.
