play a different action, from a list of pre-made ones, in order or randomically.
Add action (+) button: shows a list of pre-made actions;
Play random checkbox: if disabled, each action from the list will play in order.
For example, if list contains actions A, B and C, when executed the first time, action A will play. The second time, action B will play, and so on. If checked (to play randomically), an action will be randomically selected every time the interaction triggers.
Delete button: remove the selected action from the list.
