Remove extra gap between open programs icons too

The "Taskbar Items > Pinned items > Remove extra gap between items" function currently applies only to closed pinned programs. It could be good if it applied to open programs too, both pinned and not pinned.

One could also say, though, that having even dozens of icons "without extra gap" could leave much unused space beyond the rightmost icon: an "auto-sizing" function could be needed in that case, to always benefit from the whole empty taskbar space.
