My only issue with ObjectDock is a loss of functionality in Windows (going back many versions, but still available in Windows 10). If you shift right-click on a consolidated entry in the Windows Taskbar (say, 3 command prompt windows), you get a context menu with several options:
Cascade all windows
Show all windows stacked
Show all windows side by side
Restore all windows (this one is normally grayed out, unless you've used the next option)
Minimize all windows
Close all windows
These only apply to the specific application, not every visible window. This functionality is something I often use, but which is absent from ObjectDock, so every time I give it a try...I find that after an hour or three, I'm uninstalling ObjectDock again.
