So no way to get it "on top" ?
Perhaps a mix for Fences if it's not docked, keep it like it is, and if it's in docked mode with roll-up it use the engine of ObjectDock with On-top feature ?
Object Dock works at the same 'level' as any normal 'Window'. It is all about what is known as 'z-order', or the layers on which various objects/features/functions of the Windows OS can function.
The lowest visible layer of the OS GUI is the desktop wallpaper.
Next on top comes the desktop Icons.
AFTER those comes the program Windows.
Next one would be the taskbar/start menu ....with the capacity to be placed above open Windows, etc.
For a third party program to relocate or change this order, the actual Microsoft Windows format for the icons would need to be stripped out and rewritten at a new layer, something I expect cannot be done whilst still maintaining the Windows Shell [Explorer.exe]....
