Let me start by saying that I love Stardock products and have been a subscriber for years across numerous offerings.
I've recently thought of a couple of features that I think would make good additions to the Fences program.
I'd like to see the ability to "stack" multiple fences in one Fenced area. To keep individual fences separate, I'd suggest that each Fence be given it's own tab which could then be clickable. Make the tabs able to be placed on the top, bottom, or sides of the main container so that getting to different layers of Fences would be just a click away. I'm thinking of something akin to the vertical tabs that we are now able to use in most browsers.
Another suggestion I have is to make the background of each Fence area customizable. Whether a single color, a gradient, or even an image of our own choosing with options for opacity. Doing this would make Fences more distinguishable from each other than simply using the area's name as we do now. It would also allow for greater customization of our user desktop spaces for those that like to fine-tune every little detail.
I really hope someone sees this post and likes these enhancements. Please feel free to reach out any time for further input or clarification.
