Feature Request: Enhanced Window Arrangement

This is a feature request to support window arrangement within Keyman Developer for better developer productivity. Keyman Developer presents an overlapping view of "tabbed" windows. The request here is to support:

* Re-ordering of the tabs (drag the tab label left or right).
* Horizontal and vertical arrangement of windows.

The 2nd item allows for easy comparison, and copy & paste, between similar keyboards. The attached screenshot shows how this feature is supported in Eclipse for two windows (note that two is not a limit)


It appears that window minimize and maximize may be supported -? I find under the menu option: View > Expand Editor , and a corresponding toolbar icon for the same, mapped to F11. However this feature is always disabled (grayed out) and I see no way to minimize a window (working under Windows 10). Apologies if I'm overlooking the minimize mechanism.
