One of the deciding factors for loading Linux Mint or reinstalling Windows 11 on my niece's first computer, will be Middle Click Paste.
It will only confuse her, esp given how some laptops have a middle button on the trackpad and I worry about her ability to regulate her pressure on the scroll wheel.
I haven't found a simple way to turn it off entirely, even the option on the DE doesn't change the applications, as it's per application changes. I could disable the middle button entirely in the command line, but that doesn't work for devices that are constantly being unplugged and replugged in - thinking of a USB mouse on a laptop. Requiring me to install a daemon is out of my depth, and tbh shouldn't be necessary.
I hate the idea that this hasn't been fixed for normal users, that there is so much resistance against fixing it - middle click paste is fine for superusers from the early 90s, before scroll wheels were a thing, but normal users hate it.
