I suggest, if possible, to add an option for arranging an application's multiple thumbnails either vertically or horizontally. Normally when the task bar is along the top or bottom of the screen, the thumbnails of a program with multiple windows will display horizontally, but you should be able to choose to show the thumbnails vertically, stacked one on top of the other. Similarly, if you have the task bar along the right or left side of the screen you should be able to show the thumbnails horizontally instead of the default vertical arrangement. Perhaps you can add this option to your utility.

I will see about that.

That would be a bigger pain in the ass. They already get in the way of my mouse when I accidentally hover over them.

The delay parameter doesn't work for me.
