Yasnippet can be magical. Would love to see your usages in action.
Here’s one I really enjoy using https://xenodium.com/smarter-snippets

Very nice snippet! I don't have too many advanced usages, most of them
just look like:

    # -*- mode: snippet -*-
    # name: insert new interactive command function definition
    # key: interactive
    # --
    (defun matt/$1 ()
      (interactive)
      ($0))

But I do have one neat one which powers the
[library](https://mjdiloreto.github.io/books_i_like/) on my personal
blog, which creates a custom org-mode block that exports to the HTML
for each book:

    # key: book
    # name: book entry
    # --
    +begin_src book :title $1 :author ${2:$(apply #'concat (mapcar
(lambda (w) (substring w 0 1))  (split-string yas-text)))} :cover-url
    ,* ${1:title}
    ,** ${2:author}
    $0
    +end_src

Whatever I type after $0 becomes the book's review when you click on
it ;)

Neat idea! Btw you can modify the `yas-new-snippet-default` variable
to change what yasnippet inserts into a new snippet buffer. This
itself is a snippet though, so don't forget to escape $ and `.
