Now, I would personally like to toggle between having an option to use a reaction and receive a prompt asking if I want to use one to be set for each individual character.
For example, a fighter would be toggled to use Attack of Opportunity as their reaction and I would just set that for them and call it good, whereas a wizard or a bard I'd like to have the option to choose on when they use a reaction.
If I'm in a combat scenario and there are multiple spell-casters. One of them is the boss and two of them are minions, I'd like to save counterspell for the boss in the event one of the other two is before him in initiative (or after my character's turn) because I think it'd be more likely that the boss would have better spells, so I don't want to just counterspell the first spell that comes as soon as I have a reaction available.
