after restoring the system back to version start11 v1.1 now back online:
My version is Windows 11 Pro Build 22000.593 (no beta, insider...), latest regular release
Apart from the scary offset taskbar appearance: yes, I was aware of the taskbar center alignment issue before, though haven't found out where this mysterious "enhance the taskbar" option is. Maybe you can post some screenshot. Anyway, it's not an "enhancement of the taskbar" to reduce/disable standard functionality provided by Windows itself or a previous release.
All settings worked well in version 1.11 and after upgrading/updating to a newer release one can at least expect that the software behaviour won't change - till options are actively chosen by the user.
Version 1.11: Everything fine, center alignment works.
Update to version 1.12, no change in settings: No center alignment anymore, option grayed out - no explanation why that is.
But hey: you "enabled" the "enhanced" option, so this is why we have to "reduce" functionality.
I guess you get the point?
Appreciating you work nonetheless.
