Old Form Builder with right column
This means in future that you can edit any component, just by clicking on it and editing it in situ.
New Form Builder with all details in centre column
The new layout should allow you to edit your questions with easier detail as you now have more space.
It also means that you can now avoid switching from the centre to the right hand column, as all details are contained within the one area.
This will finally allow us to provide a responsive design for all users whether you are editing your forms on a desktop or mobile environment, this responsive layout is coming very soon.
