I believe that the icon spacing on the taskbar (the space between any two icons) is too much. i have like 10 apps pinned to the taskbar and its now full. So Team Zorin , please try and make the icon spacing right on the next release (Hopefully, the next release comes with gnome 40 and some taskbar improvements =] )
They should make the icon spacing adjustable. The only thing is bad about the taskbar is that I can't minimize tray. I also realize when I full screen, the panel doesn't show.
