I would like to see the ability to group applications together into App Packs or Template Groups for easier assignment. Templates are typically build around a specific application so it doesn't make sense to put all of the components you want to monitor into a single template. With that being said, when you have relatively standard deployments you are almost always assigning the same sets of templates and this is where this feature would be handy. Instead of needing to select the same 5 different templates for my deployments I would only need to select the one App Pack that contained all of my typical templates.
Please provide any feedback you might have on this, thanks!
