It is a widely adopted practice to not share specific dates in long term planning and it would therefore be helpful if I could hide the dates/timeline in the gantt view.

The only option today is to zoom out but that is not practical as the feature-bars will become to small and the timeline is still visible but in years.

I want to be able to show how feature A is scheduled before Feature B and that it is dependent upon Feature C being completed without having to show when the features will be worked upon.

Simply hiding, or making the dates blank, will do just that.
