Please consider being able to put a project in a "planning" / "template" mode so when tasks are assigned to resources, the resources' time is not committed and tasks don't show up in the different views until the project is made active. Perhaps add another level to the workflows above the Active level, so any status in that level would automatically make the assignments and tasks "tentative".
This could be helpful when planning and making templates so the resources are not yet committed and resource levels can be forecast. The "proposed" or tentative time could be displayed in a different color on the timelines to represent time of that nature.
Thanks for any consideration (and votes)!!
