Question: Move Take Back

[Imp]

I have gotten into the habit of saving every move after the first move

Assume you meant every turn.
No need the game saves that automatically
This is a useful feature from time to time such as when your game has been interrupted by real life & you have a brain fade moment upon returning.

[Gelainey]

Not just at every turn, but at the end of each phase of the battle. For example, I may be advancing on two axes, one a feint, the other real but as yet unseen by the AI. I will move one group, save, then move the other. I use two save slots only, one which has the name of the battle, and another the next save slot below which I call "see above". I can save in "see above" as often as I want during a turn and this avoids the frustration of having to start a turn from the beginning if I miss click or hit the "A" button by mistake, for example. I only have to repeat a particular phase rather than a full turn. I suppose that this only matters in larger battles where there are lots of units on large maps, but I find it a great time saver.
