This is part of the ChasmGui instructions.
To create a new state, the best way is to hold down the shift key and click on the open concept to create a new untitled state.
To rename the state, double click on it and use the dialog box to change its name and description. Hit the save button so save it.
To delete the state, double click on the state and hit the delete button. A window will pop up making sure you meant to delete the file. NOTE: transitions into and out of the state will also be removed.
