Review on Marionette by Mark Morrow

The concept is very clean, easy to use. It makes it so that I can focus only on my business logic without worrying about how to render HTML elements. This tool also has support for AngularJS which is great since we are using this in our project. We haven't encountered any problems yet but we do have plans to create more complex projects soon. There's no need to write extra JavaScript files when creating templates or adding new modules to your app. You just drag them into one file and you're good to go! Also, there's nothing wrong with having multiple CSS stylesheets. Having all of these in one place allows me to keep track of changes easily as well as organize everything nicely.
