It doesn't seem possible to change the a starting state node to a normal state node, or vice versa. e.g. if you have a starting state with transitions to a number of states, but you want to insert a new starting state before it and convert the present node to a normal "State" node, it looks like you have to

• delete your current starting state node
• create a new state node with the same name, transitions, actions etc
• add your new starting state node

Since state and starting states are very similar, perhaps we could have an option to convert a starting state node to a normal state? e.g. in the properties tab at the bottom perhaps? Then you could just click this button or change the option to convert the node type, without any deleting and recreating.
