not that they really bother me but I am never going to use them and I am just nit picking here now.
In the case of tour, yes, but like the Windows App Support, you'll need to come at them from APT.
sudo apt remove zorin-os-tour-video
sudo apt remove zorin-os-lite-tour-video
sudo apt remove zorin-os-tour-autos
Those three should get all of the tour possibilities. Help is another matter. I did some exploring, and while zorin-os-docs can be removed, doing so put ubuntu-docs on, and the icon didn't go anywhere. Both are read by yelp, GNOME's help document reader, so I looked into removing yelp, and Synaptic wanted to remove zorin-desktop with it! At that point I decided it was time to slowly back away. With luck, someone else might have a means to remove help, but I don't recommend the obvious route due to the side effects I mentioned above.
I've said it before and I'm sure I'll say it again: removing unwanted icons is a pain point that I hope is addressed in future Zorin releases.
thank you for the fast response that just got the tour app removed.
