It would be cool to have animation event tracks not only for current control, but also for child controls. For now if i need to trigger some event on different controls in some sequence I need to make custom events in UMG widget and call control events from them. Animation event track nodes can have not only name of the event, but also reference to a control on which that event should be executed.
Also it would be cool to have a dropdown combobox with custom events in that node properties to select from custom events, not just an edit text field.
