I switched to the beta of Win11 just so I could start using ungrouped taskbar items when I got tired of waiting for explorerpatcher to be updated. It is still a bit janky but I'm so glad it is there.
I don't get why they removed this in the first place
They rewrote almost all of the Taskbar code for Windows 11. This was the first major update to it since the introduction of the Superbar in Windows 7.
