@Michael Karam1,
The new App is more flexible. Up to the user where they like to open it.
It can behave exactly the same as the old preview if the users place it on the right side of the screen as a side panel.
It will reopen every time in the same position where it was placed.
The shortcut can be placed in the taskbar or on the desktop. (We can also use a "Hot key" combination to open Copilot)
Personally, I hated the side panel and the bugs that came with it.
I think they changed it based on the feedback that they got from many different users that did not like the fixed location, on the right side of the screen. 😂😂
(I believe they stole that silly idea of the fixed Side Panel from Apple. 🤣🤣)
After all, this is called Windows system, not Side Panel system. 😂😂😂
