Time advancement in mission editor

[Capn kamikaze]

Would it be possible to add a feature (with the ability to activate/deactivate) to the mission editor, so you can use a time-slider to preview the unit icons moving around the map following paths between their waypoints, so you can see where they would be if they were just flying/driving/sailing around but without killing each other, seeing weapons being fired would be helpful too, eg rockets/artillery and bombs being dropped.

The point is to show the pace of the mission to the builder to highlight were the action is happening, to make it easier to make longer missions with a more consistent pace.
