The best part about this tool was that it had everything I needed for my job - from designing forms with tables/checkboxes etc., through editing xml files as well creating custom controls like drop downs list boxes or even buttons! It's not so easy at first but once you get used its just great!! And yes there are many other features which can be added such us drag n'drop functionality between pages within same application etc..
Also they have good documentation where we could find tutorials…
