show modification/created date when list=”true”

Thanks for the great plug-in. I would like to show modification/creation dates of child pages, but show_date_modified="true" does not seem to work when list="true". I managed to make it possible by patching the plugin source code like this: https://github.com/prg-titech/cc-child-pages-x/commit/c601a4047c67515f8b4c8e5f9358c5b86c2ca9ed . Would there be any chance if this patch can be incorporated into the official plugin?
