Ok, lets see if makes sense
See the Orders box bottom left of the screen.
It has two sections, an orders section and a movement section.
Above that is the Edit Tasks Dialogue box. These work very closely with each other.
The Edit Tasks Dialogue is a detailed display of the properties of the currently selected marker (waypoint) on the map, or after selecting an order from the Orders box, contains the detailed information of the next order to be placed on the map updated to include some default settings and some stickied settings carried over from the last order.
For those that didn't know a probe order is just an attack order, but with a different set of default settings (min losses instead of normal). These settings can be changed in the Edit Tasks Dialogue to match those of an attack if you wanted to.
The Movement section of my proposed orders box is just a move order but with the default settings for that particular move formation.
So if you just wanted to move your units from one location to another you would just select the formation icon of your choice from the movement section then click on the map to place the marker. If you wanted to change something else like the speed or timings, you would have to set them in the Edit Tasks Dialogue.
This will help to save you having to dive into the Edit Tasks Dialogue for a simple change of formation as you lay your route and give you a visual reference with that formations icon on the map.
The other task type of orders (attack, defend, withdraw etc.) would use the formation selected in the movement section to move to the task location, similar to how it used to be.
