There is a field for executable tasks, it looks like a little gear icon. By default it is included in our scheduling view (the field is simply called "Executable". All you need to do is add it into any of your views and you can then sort and filter by this. It comes in really handy, especially if you combine it with filters for tasks that are past due and on the critical path (these tasks will delay your project for every day that goes by where they are not completed).
