so we already had a thread on this and my opinion is the same as it was back then.

I dont like the menu popping up every time you have the ability to do this. Why? because it slows down the gameplay. Once for On hit actions but doubly so for reactions.
Having to tick a box for "i dont want to do my opportunity attack right now" any time a goblin moves next to you would make my head hurt.

The solution is simple:
when an enemy does an action, you press a button. If you press the button a context menu pops up and you get to choose a reaction.

Simple, easy, elegant.
And since Baldurs Gate fans are used to real time anyway i dont think anyone can complain that its too "Action oriented"
its basically how it works on the tabletop.

You could always have the option for it to always automatically pop up if you want.
But i dont want it to be the default, it would slow the game to a crawl.
