Task Scheduling

I am testing Smarsheet. I am satisfied with the task dependency support but noticed one thing I am not liking and that is - if I, for example, enter 4 tasks and add the dependencies causing the dates to adjust accordingly -- then remove a dependency on a task that got pushed out, it will not auto schedule itself back to project start date. In order to do this you would need a known project start date and an auto schedule feature (like ms project).

What can you tell me that would make me feel better about this? thanks.
