There are many ways of disabling events. Toggle disables, On start of layout (event disable), Group disabled and others like sprite behavior on start disables. Depends on what you are trying to do. As to where to disable the feature.
Like I said in the previous post I was looking for something other than disabling using event sheet, rather a temporary hide option like with layers, but one that could affect the effect once in runtime. Less work than going in and looking for code or clicking on a few lines to add code into event sheets. Maybe Im a bit fussy, its just that I got used to temporary disabling different options in this manner, which is more intuitive.
