The widget tool is a powerful tool for interface customisation. Use it to create your own editor based on a document (project or compo).
Create a widget tool in the element tree. Then, acces to its Component editor. Switch on EDIT mode and drag an drop parameters inside.
Customize the size of each element to create the perfect layout.
Note that some parameters have designed widget that allow you to access more option for controlling them.
For example: percentage can display their own curves and integers give you access to mathematival operators.
