I've tried to get it stable, but currently it is horrible.
If I'm telling Fences to put also Documents into the "fence", I can handle downloads.
For example: If I extract a file on the desktop, the extracted file will be moved to the left upper case over the "This computer" icon...A workaround for this is to not have something there or to extract files somewhere else. Both are not acceptable, because it works with the normal desktop.
Here Fences must check the grid and which positions are "occupied" by any icon/folder something else. It can't be so hard to move new items in a grid into the next free position by checking in first order from top to down and secondly from left to right.
Also if I move a file from an open archive to the desktop with the cursor I want to determine where the file is located on the screen (the point where I drop the item). Currently Fences is showing me the icon for less than a second and then it is also moving to the upper left corner.
