I like the second one best
A couple of questions:
What will the in-battle item window look like?
Does each character have their own inventory space or it it all just one space for all items, weapons and armors?
The in battle window will look the same, but I will probably make it impossible to equip items or move items, or I might make either of those actions use up a full turn just as using an item will.
Each character has their own inventory which they take with them when they leave.
Also, here are some new versions. People say they like the mix of colours and lines on another forum, so I made up these
#4
#5 (Zeriab's idea)
I think I will probably go with #5 and make it easy to change background colours.
