So, it queue fights upon contact with enemies. So, if you are having battle after battle with no break in between that means your party members must be repeatedly close to enemies. You should if no battle are queued able to bring up the menu. If that not the case, please tell me. I thinking I should maybe instead handle the battle differently because it can be overwhelming, however I only ever had maybe 3-4 battles back to back, so it wasn't horrible.
The lack of morale bar in the menu was a design choice, which I get a lot of hate for... plan to add future aspect to provide some benefits. But the idea was the morale is in the battle only so you have a reason to watch the battles. With the morale bar being in the menu, you could easily skip the battle entirely and just catch up on the changes in the menu at the end of every battle.
