What I am thinking about is slightly different. A scheduler really only looks at tasks, and the problem with that is that they don't know anything about the data that the tasks operate on. So looking at tasks only doesn't give you a good view of your data flow. I've used schedulers for a long time, but they tend to get really messy as well. But yeah, you're right that people are used to schedulers and they'd probably expect the kinds of features I am thinking of to be in there as well.
