I've created a custom post_type plugin. I would like to add a custom filter to the main list page that is displayed when you first click on the menu item in the left-hand menu (see image). But, I can not find the code that makes this list or how I can create my own code to replace the default page.
Also, I would like to add functionality to the delete (either individual post or bulk action). I want the post to be deleted, but I also want to delete the Gravity Form Entry for this post.
I've searched so many sites that I'm starting to confuse myself! :) Any help would be appreciated!
