Stop application icons displaying with alt-tab/everywhere

view story

http://crunchbang.org – I've recently started using #! on my main machine and I really love the minimalist look, but I'd like to make it a little bit more minimalist. The main thing I want to do is stop application icons showing when I use alt-tab or (windows)-tab to switch windows. Is there any way of doing this? I tried removing all the icon themes from /usr/share/icons but that doesn't remove them from the alt-tab list.I'd also like to remove all the file manager icons as well if I can (I use it in list view), as long as it doesn't just leave blank space where they should be.
