IB.CMS - content management system with ExtJS admin panel

Recently I completed work on CMS with RIA admin IB.CMS. I want to introduce my product to the Habr community. Under the cut - a brief overview of the system in the form of screenshots. For more information about CMS, you can read on the website http://cms.ibpro.com.ua/
View demo site can be link http://demo.ibpro.com.ua/

There is access to the admin panel - http://demo.ibpro.com.ua/admin , to obtain it you need to register. In demo mode, you can change the content of the site as you wish, but every half hour it is restored to its original position.

In the comments, leave your questions / wishes / found bugs. Any constructive criticism is welcome.
PS If among you there are those who wish to order a website on this CMS or RIA-application on ExtJS - write in a personal / call Skype.
UPD For all kulhackers, a big request - if you find a hole, you don’t need to break anything demonstratively, just write about vulnerability in a personal.
UPD2 A big request not to troll in the “why is it necessary” style, but to comment only on those who are really interested in the product.
