Hey, as pointed out in the text that shows up when you are about to create a topic, you should only suggest one feature per post, and check for already existing feature request posts. (The toggle disable single actions/conditions was already requested)
So, you can contribute by leaving a like on their post and commenting about how would you think it is useful: Ability to disable specific conditions or actions within an event
Also, probably Lumi or any other moderator will ask you to edit this post and choose only one of the 5 requests you provided.
