I've lost a long text-in-progress yet again by using the "quote" button. In reasonable systems, the quote button appends the text to your comment field, meaning you can quote one comment, add some reply, then quote another comment, add another reply, and then hit Send. On Pagure, the quote button replaces everything you have in your comment field, and there's no way to put it back (ctrl+z).

Please make the quote button append, not replace.
