In lot of situations I wanna disable/enable object effect, but you can only delete it. It would be really helpful if you could control their state with boolean or something. Simply mark them disabled/enabled, and add button functionality. I believe this would benefit all of us.
As an alternative/interim option: While you cannot do it through the GUI, keep in mind you can enable/disable effects via events.
Yeah I know you can do it in events, but it would be cool if you could do it in editor.
