Thanks Variscan !!!!!!
Thanks because you wrote exactly what I want to write but, as my english is not so good, I was trying to explain in more concise form.
Farshad has worked a lot and produced something really very very good, he has always made a great deal of assistance, always free, so far.
I'm really surprised and disappointed that, when he ask for financial support to complete (to our advantage) an agreement with Sencha, someone has written things really unfair.
Farshad, many thanks for your work.
I will definitely will purchase UniGui.
