I've just released a new version of obsurvey. This time it's the survey editor that's been updated. Now ther is no longer a toolbar for inserting questions. Instead buttons for adding questions appear above and below questions when you hold the mouse over them. When you click the "Add question" button, you are asked to select what you want to insert. The selection items are those that where in the toolbar before. Select one, select several, rating, text (single line), text (paragraph), text (not a question) and pagebreak (not always). You are also given the option to delete.
Let me know how you like the new editor. Go to obsurvey and try it out.
