Sencha Touch and Kerio Workspace

Kerio Workspace is a powerful and complex web application that heavily depends on HTML5, CSS3 and Javascript. The interface is designed for desktop browsers on PCs and Macs, so when we decided to provide mobile access for smartphones, we needed a different approach. In version 1.0, we experimented with a very simple interface in plain Javascript and HTML . It worked, but it wasn't very visually appealing and provided only a mediocre user experience.
