Emacs Lisp and menu packages: dmenu, hydra, posframe, transient, etc.

Let's get together virtually again on a Friday morning (US Pacific Time) to discuss Emacs menu packages and related or unrelated Emacs topics.

If you have something to give a short demo of, that would be appreciated. Open to all levels of Emacs users.
