Another thing that would be really great would be if we could have a "divider" that we could insert a space or gap in between groups of icons on the taskbar.  Or maybe divide the icons up into "zones".

I am trying to create a "dummy" program or shortcut to a program or file that I can put on the task bar with an edited icon such as a small dot (or even blank, if that is possible) to create a space between other icons and give them a grouped look.  I can't seem to put shortcuts to files or programs on the task bar.  I also tried to pin a program that I never use to the task bar and then change the icon but I can't seem to find anything that I can change the icon for.  The goal is to create a divider on the task bar that puts a space or gap between a few groups of icons.

Any ideas?
