Notification by category

- Notification by category allows you to notify only when a file is added to the category. it would be necessary to add the possibility of notifying also in case of addition of file in the sub-folders of the category

- Possibility of having the complete path of the category in the email including the subfolders. if you have several categories with the same name, it is difficult to find the category in which the file was added

I think it requires more development but it would be necessary to be able to notify emails that belong to a WordPress role or to have the possibility of notifying a campaign list such as mailchimp or others
