I'd love to have this option.
I have a "deferred" list, things that cannot be started right now, but which have to pop up in the (near) future. Therefore, I use the Start date and a Smart list on tasks with such a Start date. However, the Start dates are not visible in the list, and as such I cannot sort on it. This makes the list a lot less usable.

I'm still interested in this feature, RTM-team! 😉

I'm still interesting in this feature too!

I'm also interested in this feature.

2017... huh. You can see why so many people eventually leave RTM.

This feature will make the app more customer-oriented and allow users to manage their daily tasks, list, tags, and everything around it.

For example, having a list of tasks with their duration will allow you to decide when and what to start.

Another example is comparing the priority and duration will be much easier to decide where to start, in other words finishing something big (one task) or several small studies carrying much more value for the user.

I personally will have at least 4 columns -> task, due date, duration, and priority or start time.

I hope this will happen soon or latter, and I'm very sad that this is not supported.

Would it be sooo difficult to implement, RTM?
