Currently, if an instance object has more than one of the same behaviors(Timer, Tween...), it will very scary to modify in the action event list. I recommend merging them. Add an option to choose which behavior.
For example, when I The Sine 'Set enabled', add a 'drop-down list' or 'input box' to choose which one it is. Just like the 'set effect Parameter ' event action.
When different family objects use Timer or Tween behaviors, it becomes very inconvenient.
Timer or Tween doesn't matter, but Sine behaviors does need to add a lot of.
Why would you end up with multiple Timer or Tween behaviors in the first place? You only need one.
