Me on both desktop and PC, but I don’t think I’ve had 10 windows open at any one time tbh. Or that any particular DE would perform significantly better if you really needed to work with 10 windows simultaneously. That’s a problem I would fix with additional monitors.
I would also have windows snapped to half screens on the workspaces, so I really only need 5 workspaces. Considering I have a 3 monitor setup at home, I don’t think I’ll have too much of a problem since I can have 6 windows up at once. Still, juggling 10 bloody windows is going to be annoying whether it’s GNOME or not.
The permission to do admin things is given by the root user, to your account. So you have to verify your identity by entering your password.
Isn’t that how it is? I though that was analogous to how almost everything worked IRL. Whether withdrawing funds from a bank or engaging government services, you prove your identity as a customer/citizen to get the relevant services. At no point do you login to bank or government computers with full privileges.
