I would like to throw in my suggestions for a ‘real’ Gantt chart in the Activities -> Show Timeline For window.

This would mean being able to select not only the end date of the Task List or Task, but also the start date since that would give you the capabilities to actually state that a specific task should take: X or Y days or should be done in conjunction with or after another Task List or Task. Currently all tasks start on day 0, so there is no way to gauge how long a task should take, or is scheduled to take in your project.

One of the cool features of the current design is the ability to drag the end date of a task from the Show Timeline For area. What would also be really useful and could be done in conjunction with the above is:
1) to be able to add Task List and Tasks directly from the Show Timeline For window. (Currently we can modify the current Task List and the Tasks within the list)
2) be able to re-sort the Task Lists and Tasks from Show Timeline For, like we can directly in the project blog
3) then be able to select the start time, such as start at end of previous Task List or Task etc.
#1 and 2 seem like they could be done pretty easily since this functionality is already available in the other windows. #3 is more of a substantial change I suspect

Last request somewhat related to Task List: Have the ability to assign a Task List to a person and that would then make that person the default Responsible For in each of the Tasks. This would just save selecting the responsible for for each task if we have a long list, or if you forget (not that I’ve ever done that and wondered where my task went - hehe!!!)

Would anyone else find these features useful?
Any other ideas for this area of Solve?
