For your first two points, I'm kinda against having to fight against the system, at that point I prefer to work alongside the system with Linux, but W/E. In any case, I would have fixed these if the taskbar wasn't impossible. No I'm not going to install a 3rd party program to fix the taskbar.
About the 4 monitors, it's cool that you like having 4 taskbars, wasting tons of space. I don't. I'm not asking that, I'm asking having a single taskbar vertically. It's one of the big complaints I've read about win11, not being able to have vertical taskbars on the side of the monitor.
I've not seen a way to remove the "recommended" space in the start menu, and I'm sorry but any recommendation I didn't agree with is an ad. You might think otherwise, and that's cool, but I don't like ads in products I pay.
That last sentence wasn't very nice, especially considering that you didn't understand one of the complaints (the taskbar thing).
Anyway, happy that you are enjoying win11 and I wish I was, but yeah, I don't fancy paying for less features.
