I would also like to leave a big "Thank you" for this tool! I'll use it for a while and if it works fine for my use cases, I'll donate!
In my case, I have a 2-row task bar (grouped launcher Icons on the top bar, running applications on the bottom bar). Also, I am using the great VirtualDimension tool for multiple desktops in Windows (as a UNIX user, you'll want this badly), because it runs on Windows XP and all the others up to Win10, and its super fast and low on RAM usage. Now I wanted to put VDim over my task bar, but both are "always on top". When I click an icon or application on the bar, VDim would get hidden, because the task bar overrides its "always on top" with its own.
But removing its always-on-top feature sucks, because then, fullscreen windows would cover the task bar as well! Damn!
And this is where Desktop Coral comes in! Docked to the bottom of the screen at 0 pixels height, it can protect my task bar from full screen windows when I remove its always-on-top flag.
Now VirtualDimension is embedded into the taskbar in a stable fashion, always showing, and windows maximize as if the taskbar was still always-on-top, exactly the way I want!
This is what it looks like, protecting my task bar to have VDim stay on top:Usefullness
