Created attachment 176907 [details] Calendar is a separate window, while the rest uses the same window. Clipboard, Battery, Internet, and Audio widgets transition smoothly between themselves. They seem to share the same "window". However, when going from the Calendar into any of the previously mentioned widgets it has a rough transition. I'm requesting to make the Calendar's "window" smoothly resize into the other widgets.
The system tray items transition between each other because they're all in the System Tray, which technically is a single widget. Transitioning from one widget to another one cannot be done in the same way for technical reasons, unfortunately.
