Demo updated! Again!
Attempting to add a character into any empty slot will move the cursor to the last available position. This includes when the party size is less than the maximum that is possible.
I’ve also looked into the font size discrepancy when it comes to using skills, or items, outside of combat. The font size seems to vary somewhat from class to class, but, at least the relative size adjusts according to the maximum number of party members.
There is additional handling for hidden/inactive characters. What this ultimately means is that inactive characters can use skills, and be the target of items and/or skills outside of combat. They also would not be considered targets in combat.
Thanks again to Malandy for the bug reports, and spelling errors!
