We would like the ability to completely undock the chat window from the main window to where you would just have your cards on the left and contacts. Then in a different window, have the spaces and messages. Currently, you can only open a single space into a new window but that does not undock the messaging portion from the main application.
This functionality is currently in jabber and many of our users have requested this functionality in the Webex App primarily for the purpose of real estate on their screens. Users are able to shrink their chat window in jabber and minimize their contacts.
