Yep, that's the idea.
With a savegame for each turn of a battle, it becomes possible to track the progress of the battle turn by turn:
- By looking at the different 'Turn' tabs turn by turn.
You can use the green left/right arrows at the top, or the Ctrl+PgUp/Ctrl+PgDown shortcut keys,
to move from one turn to the next (or back). This works especially well for the 'Strategic map', I think.
- But on another level, the 'Battle' tab, having savegames for each turn gives much more depth
to the battle unit history and MMAS tabs.
