This package includes two .exe file, just having icons and doing exactly nothing. ...
How to use:
just pin your preferred, to your taskbar and drag it where you need, to separate your pinned icons.
1) one of these, has the icon looks like the original taskbar sizer, [ which you see when you unlock the taskbar ], and the other has a transparent one, mimics a space between icons.
2) these programs are developed with c# and simply do nothing, simply exit if clicked.
3) you can create shortcuts for these, as many as you want, and pin them all to taskbar, for more than one instance of the same separator.
I'll be glad to see these tiny applications feet your needs.
