We had built a application using Ext JS web desktop. Something similar to:
The application is basically a web based administration panel which has many modules(Around 20 modules). Each module is a Ext JS window and you have numerous options that you can change. The clients were using for sometime. Right now they are saying they don't quite like it. They quite liked the idea of the desktop when it was first introduced. I'm thinking that their main concern is that the application kind of looks too much like a windows application. They don't like the extjs grid etc. They had casually mentioned that they quite like the interface of basecamp PM tool.
My options are to keep the desktop as it is and redesign the windows so that they are more usable. Most windows would list a entries on the left panel and on clicking a entry the form on the right gets filled up, which can be edited and saved.
Do you guys have any suggestion to redesign the desktop app into something else. Keep in mind that this is a enterprise application used to configure some back end processes, display some realtime statistics etc.
