Front-end improvement

Arrange the layout to be tidier

[har07]

Maybe along the following layout :

• XML editor, XPath/XQuery editor, and output 'editor' are resizeable.
• editor label on the top right corner slides to the right when the corresponding editor receives focus, hiding most of the label body to provide more room for editing.
• format button on the bottom right corner goes translucent when the corresponding editor receives focus for similar reason.
• XPath/XQuery dropdown might be implemented using 'Navigation' button -behaves similar to radio button- instead of using dropdown/combobox control. See below (capture from Flat UI)
