I must say that the EXT designer looks great. I can see that QT framework has been used in the built and it just looks great. I was wondering if the toolbar that is dockable and contains the accordion style controls is something that you guys have created from scratch or was it part of some QT widgets?
Also is there an open source version of Ext Designer so we can maybe have a look at some of the components and learn something nice. Its is a greatly designed application.
