The MSi GT70 Dominator is a high performance gaming laptop. Whether the HDD spins down or not is not obvious. Perhaps when I an running on the battery, there may be a delay as the drive spins up, but I am willing to tolerate that. The real issue is having to do things like hack the registry in order to point WindowBlinds to a folder on the HDD instead of the SSD. A simple modification to the Stardock desktop apps to add a setting that points the data files to something other than the default location is neither unreasonable nor difficult.
I speak as a retired senior software engineer with experience in everything from x86 assembler to C# and as a Windows/Linux/network administrator. Although my main focus was scientific control system applications and utilities, I did my fair share of Windows applications.
Now I discover that SoundPackager and IconPackager will not install on Windows 8. While DeskScapes will install, it only displays a black screen. Not only is Stardock support downplaying my perfectly reasonable suggestion, they are apparently not supporting Windows 8 or presumably Windows 10. I guess I can save some of my retirement dollars by not renewing my Stardock or WinCustomize subscriptions.

Would your high performance gaming laptop have Intel graphics? There is a known driver bug with those which causes Deskscapes to show black. This is a problem at Intels end not ours unfortunately and only showed up with recent drivers.
Regarding your other issues, I suggest you read this : https://msdn.microsoft.com/en-us/library/windows/desktop/aa365006(v=vs.85).aspx
Storing those files on another drive is an edge case that almost none of our customers would require, but the tools are built into the OS for you. There are good reasons for us keeping things in one location and changing the registry keys for WindowBlinds is also totally unsupported as they are leftovers from the pre Windows Vista days. I am sorry this isn't what you would like, but I hope you can understand that whilst your needs are very important to you, this particular need is not overlapping with the rest of the customer base.
