The taskbar icons in windows xp/vista (i'm using vista, but this would be useful for XP too) cannot be reordered which is frustrating at times. Sometimes I launch apps in a particular order just to get the icons how I want them! It seems silly to me that they can't be dragged and dropped to rearrage them.
Also, in a potentially separate, but also related, suggestion, often program icons are grouped into a drop-down (drop-up?) menu when I'd rather see them separately still. That is, I'd like to be able to adjust the threshold that's used to decide when to start grouping application icons.
I couldn't find any way to do these already, so apologies if there's already a way to do either of these things. :)
