Two different dates per task: "To complete before" and "Planned for"

indacp says:
When I plan a task, I always want to know when is the final date to complete that task, however I may want to do the task one or two days in advance. Currently RTM doesn't allow this.
This feature would allow to use RTM as a task manager for the task to do, and also to know the final dates (if any) for all the tasks.
Another nice point could be that as the final date of a task is approaching, RTM automatically changes the color of the task to increase priority or indicate that final date is approaching.
