You could even have something akin to the existing on/off system for automating reaction types, but instead allow a choice between auto-trigger ( existing mechanism ), prompt-to-trigger ( my preferred mechnism ), ask-for-trigger ( Solasta mechanism ) and off. That would allow everyone to set up reactions the way they want, without adding too much development work.
3-way toggle: pop-up prompt / use automatically / don't use
Ideally with the ability to change that toggle even if it isn't your turn, in case you accidentally forget to put it on the right setting.
+1 this is how it should work
