I'm really disappointed in the center-justification of the task bar and start menu. I'm assuming that means the start menu icon will forever be creeping left as I open more apps, along with the start menu itself. Not a fan of this at all. There's an option to left-justify, I understand - and I like options - but would prefer left-justified to remain the default for users.
I assume they're building in the option to left-justify in case this move turns out to be another Windows 8 cock-up of a UI experience. I remember MS executives being "excited" about Windows 8 as well, it means little to nothing to me that Satya is excited about Win11.
