Deeply agree w ith all of it.

Now, let's discuss this backwards.

Why is it all of these are not just views of the same thing?

Imagine several tasks.

- Task view - simple list, random order.

Or, sort by duration, start date, doer, etc.

- Calendar view - show them by deadlines.

- Roadmap - show them in terms of staying on target. As well, percentage completes from the roadmaps POV.

That we don't have tools that make this easy is the sad part.
