Since the beta, the company has seriously slimmed down the size of the application: "We've reduced the minimum window size, so that those of you who prefer to keep Skype to one side of your screen, for example, can do that more easily," a company spokesperson said in as statement. "We've also tightened up the contact list, so that you can see 30% more contacts at once. We've reduced the amount of whitespace in the sidebar too. In addition, we've tweaked the way instant messages are displayed to reduce the amount of whitespace, allowing you to see more of your conversations without scrolling." In addition, the contacts monitor has been moved the Window menu, full screen mode has returned for video calls, and the chat panel can be shown/hidden when you're in a call.
