A lot of this game is preparing right before a fight so but there lacks a tool that can trigger all characters selected Abilities/Items Usage. Instead the current gameplay is a mad dash of switching between characters and waiting for each of their abilities/items usages to end each time before you can use another
I suggest a simple (in concept at least) tool that will relieve this problem. This tool would visually be a bar graph in which you can place abilities and items in for each character. When activated these abilities will trigger simultaneously. This would only work for buffs/summons or anything that does not target or damage a enemy. This could stack for multiple turns but the abilites/items would still have their natural time limit.
