I wish they solved basic things first not working well (several times after ruining a perfectly working situation) and wasting more time for me than I can gain with this copilot thingy. Like the taskbar so I could go back to the last window used when icons are grouped, not to the last opened; meeting reminders shown in the front and not under other windows burried so I only notice when the meetings already started; Teams screen sharing is updated with Teams update and not asking me if I want to update it right in the middle of a meeting when I start sharing; have the icons in the same location across Win and Mac in Outlook (also not rearranging all the time, thanks); and uncouple taskbar icons if I want so, I want this the most. Those would be the most revolutionary inventions boosting productivity.
