Oh another thing is a hotkey to exit the item drop/score screen after a battle, since theres hotkeys for everything I was wondering why I had to click exit to exit the screen. You can bind it to space as a convenience.
I would like an autosave function after every battle just in case we're too caught up into the story/grinding nonstop... And boom when flash crashes, we won't qq too much except for the 3second mishap of reloading the game ^_^.
My suggestion is that when going into combat, there should be auto targeting for the "next available enemy", while the drag and target is considered more "advanced" targeting if you get my drift. Basically it makes fighting a single enemy easier if there isn't a high priority target to switch to, and it saves some time in between waves/rounds + consumable usage.
