Well to give you more context, most of the time I used doitems +
push. and push works the "right" way. so no reversing is needed:

  (dolist (item (append (let-alist kodi-properties .items) nil))
    (push (list (spiderbit-get-id item)
                (vector `(,(spiderbit-get-name item)
                          id ,(spiderbit-get-show-id item))))
          tabulated-list-entries))

I could revert here kodi-properties I guess to get in the end what I
want?



But now I needed a iterator in the alist assigend to the elements:

  (let* ((items (cdr (assoc 'items kodi-properties))))
    (dotimes (number (length items))
      (let* ((item (elt items number))
             (title (or (spiderbit-get-name item)
                     "None"))
             (id number))
        (push (list `(,id)
                    (vector `(,title id ,id)))
              tabulated-list-entries))))
  (setq tabulated-list-entries (nreverse tabulated-list-entries))


So I would need to reverse here items and number or use something like
length - number as index?

it just dont feels very natural. I dont know.
