It's not just for "nerds" if that's what you're implying. I use the "Multirow taskbar for Windows 11" Windhawk mod because I recently upgraded from Windows 10 to Windows 11, which removed the ability to have more than one row on the taskbar.

There's a malware risk in literally every piece of software. Windows itself behaves as malware with all the telemetry it gathers.

The tiny fraction of computer users who have the capability and interest to do this qualifies as nerds in my book. I did not realize this was still a pejorative on a forum where we are mostly all technical experts in some domain or another. It is your computer - go nuts.
