And if the house is broken?
I agree with you completely. And it is not the only Gnome issue (Gnome-control-center, gnome-software, gnome software-properties-gtk) that has a lot of easy to fix bugs that go years unfixed.
Can ZorinGroup patch gnome-control-center? Maybe, I am not sure if they have access to the .bin files, either. But even if they could, can they patch all of the above Gnome App problems and constantly apply each patch after every update?
It strains credulity that they could have that kind of time or resources available, as a team of Two People supporting Zorin OS Core, Zorin OS Education, Zorin OS Lite and Zorin OS Pro.
This is addressing the very questions you asked. I feel your pain and understand your frustration. I dealt with that frustration during the time I used Gnome.
The trouble is, Gnome is responsible for Gnome apps and it really falls on us all to pressure Gnome into... at least once in a while doing what is Right.
The existence of Gnome_extensions, when they work, already covers Gnomes liabilities too much as it is.
