I'd like to put in a vote to add a 'delete link' option when you right-click a state that is linked to another event. Right now, once a state on one event is connected to another event, there is no way to remove the link unless you assign the link to another event. The only way to get rid of it is to delete the state. While the finished product won't need states to nowhere, during testing, it's nice to swap or disable links. Right now, to disable a link, I attach it to an empty state. Works, but a few extra steps.
