We need to revise Stunner toolbox before release. There are some useless buttons from user point of view as "Clear Shapes state", "Clear" and "Visit Graph". Also there are some buttons User, probably, will use a lot, for example: Undo, Redo, Validation, Delete Selected. Also there are some useful but rear buttons like Save, Rename, Copy. All buttons are in one place, several buttons are not intuitive and not possible to say what they do without Tooltips. see

Probably some help from UX team will be useful. rhn-support-eclayton, mstevens1_jira can we ask you for assistance?
