- Edit pathway is not broken... users should be able to go back and forth.
- Fix clone by sharing underlying workflow
- 'Requires some SMTP...' message should be for email action not 'Shell'
- when select a design, 'edit' button should be disabled
- Added a home button to top of editor
- 'FS' --> 'Fs'
- no i18n of 'Fs', 'Email', ... all the action names
- Allow viewing of designs owned by other user
- fix js escaping by removing escaping from title
