I see in your readme that you mention grouping.  Rather than
reimplementing that, you may be interested in what I've done in
taxy.el.  For example, it makes it trivial to define a custom grouping
DSL and a custom column-based view using magit-section.el.  See the
example "bookmarky" application:

https://github.com/alphapapa/taxy.el/blob/master/examples/bookmarky.el

It ends up looking like this:

https://raw.githubusercontent.com/alphapapa/taxy.el/master/images/bookmarky.png

Grouping keys and display columns are defined with simple top-level
forms, and these keys and columns can be customized by users by using
the same top-level forms in their configs.  For example:

  (bookmarky-define-key filename (&key name regexp)
    "Return NAME if bookmark ITEM's filename matches REGEXP, or without REGEXP, the filename."
    (when-let (filename (bookmark-prop-get item 'filename))
      (pcase regexp
        (`nil filename)
        (_ (when (string-match-p regexp filename)
             name)))))

  (bookmarky-define-column "File" (:max-width nil :face font-lock-doc-face)
    (bookmark-prop-get item 'filename))

Then a grouping "program" written in the DSL looks like:

  (defvar bookmarky-default-keys
    '(
      ((handler '(burly-bookmark-handler) :name "Burly"))
      ((directory "~/src/emacs/" :name "Emacs" :descendant-p t)))
    "Default keys.")

Turning the resulting hierarchy into the magit-section-based view is
done with a few functions in a standard way, so there's very little
bespoke code to write.

I'll probably publish taxy-magit-section.el on ELPA as a separate
package after it matures a bit more.
