I love your plugin, but am missing 2 important functions, which I think would be great if they were added.
First a really small one, because its just a parameter of register_custom_post_type() - show_in_nav_menus is just a boolean and will enable custom post types to be selectable in the menu edit screen. That would be really handy.
Also it would be great if you could integrate the possibility to have date based archives. There is a good solution here: https://github.com/Seebz/Snippets/blob/master/Wordpress/functions/register_post_type_with_dates.php
As I suspect many others are also building their own events categories and this would be so great to have.
Thank you for considering.
If anyone knows how to integrate the 2, i'd be happy to do that in the mean time.
