Hi all,
after looking for lots of web pages, I think there is not such a kind of good looking themes than can be applied easily with the format of css or sass themes. What I have been looked for is to have an opportunity changing themes easily by a list or combobox on the program and several themes suitable for Ext Js 4. Therefore, could you inform me please how can I find and apply this kind of themes on the web? On the other hand, there is an ExtJS 3.0 Color Theme Changer, v0.3 and Ext.ux.ThemeCycleButton samples on the web, but unfortunately I could not find any page like this that suitable for Ext 4.
