Thanks for a straight answer. Unfortunately, unless I'm missing something, badges are useless if the apps in question aren't in your Dock.
Badges will show up on the icons of any apps on the Home pages. They will not show up on apps that are only in the App Library.

And even for those that are, it doesn't tell you what dismissed notification were about. It's so easy to accidentally dismiss a notification, and then you can never get it back. So short-sighted.
Generally, there is an indication in the app itself. For example, Messages marks all the unread messages with a blue dot. Monarch (which you can see in my screenshot) has its own notification section that I can tap on inside he app.
If you don't want to clear the notification from the Notification Center, don't tap on it. If you tap on it, it has done it's job.
You can always let Apple know what you'd like to see here:
