Visual Tooltip makes it possible to show a thumbnail of a window by putting the mouse cursor over a button of the taskbar
The thumbnails can be moved anywhere on the desktop
The thumbnails can be added in a “dock bar”
The thumbnails can have various rotations ( from 0 to 80 degree )
( CTRL key + mouse move on dock or on thumbnails, without clicking )
The dock bar can accept all window’s thumbnails
The tray icons can be added automatically.
The dock bar can replace the taskbar.
Then, add your shortcut to the dock.
