FuZZuk,
I have a solution for you. It is a very simple hack although a bit laborious (some [including myself] would even call it cumbersome). The solution is in a post I am referencing below.
Your request is very reasonable and useful. After all, that is how we all organize the icons in our desktops. We use Fences only to put a "fence" around them and facilitate moving them around as a group as well as minimizing a given group of icons.
I made the same request and was given the same answer. From the answer I got, it seems like this is a common request. See my post with the solution I mentioned here: https://forums.stardock.com/495352/questions-about-potential-fences-functionality-thanks
Being that Fences have been around for so long and gone through several versions, I would have expected this to be a basic feature.
From programming standpoint, it seems like at the core of a Fence is a folder object that has been modified to look and behave in a certain way. So, it would seem trivial to add that functionality. In some earlier versions of Windows, Fences was unnecessary since you could create a folder on the desktop, then dump some shortcuts inside that folder, and you could later open that folder (or keep it always open) and your shortcuts would stay distributed inside the folder in any way you had freely arranged them (yes, including spaces in between them), so long as the auto-arrange option was disabled on that folder. Windows would automatically remember for that folder whether the navigation panel was on or off, the size of the window, etc. Some of this is still possible but it requires registry edits. See this post: https://www.techsupportall.com/how-to-manually-arrange-files-in-a-folder-on-windows-10-disable-auto-arrange/
Hope the info above helps you and the folks at Stardock.
Cheers
