First of let me start by saying Fences 3 is some pretty sweet software. Great Ideas.
I need to completely disable fences from manipulating my desktop icons. Essentially disable the whole sorting and organizing class for anything on the desktop other than whats located inside fences.
I've tried the options coded into context menu. It does not suit my needs. Windows sorting performs this task much better for a user that doesn't need all the bells and whistles, such as animations, and sorting rules.
If I'm understanding Fences3 logic correctly. It scans the desktop for folders and files, associates rules for sorting, if any, and sorts them into user defined fences. Also storing an xml file for reference.
One would think that this wouldn't be possible since fences needs access to your desktop to know what to store inside the fences.
I think this could totally be possible, with only losing a few capabilities. Plus a large boost to performance of the actual fences. 
Simply by dedicating folders on a drive to show up in a fence. This would remove the need for Fences to all up in my personal bubble(desktop) sorting, iterating, doing its thang. lol Let it iterate over individual folders I specify. Down Fences.... Down Boy.
e.g. Say you need a development fence to hold all your tools. The user would create a folder somewhere on their drive and associate it with the fences program. Drag and Drop would still be possible by pointing to said folder after the fence is created.
Maybe make a light mode option in the UI to enable such a setting.
I'd work up something myself, but I have my own projects to attend to.
And plus, why build something from scratch when there is already an awesome option out there, and with only a couple tweaks needed?
Please oh please!.... Don't make me develop my own. I totally don't have time. And in reference to that last statement the length of this post should quantify the importance of Fences to my development process and organization.
P.S. Plus I'm willing to bet with these modifications your user base would increase. Maybe not substantially, but it would increase.
