Hello,
So until recently (today is Nov 17 2022), Acrobat Pro had an option in the Preferences to turn off the Recent files window as default. Now that option is gone, and I wish Adobe will restore that option. Now every time my documents are closed with command-w, I get the Recent files window, and I have to close it with another command-w or manually by clicking on the window. I'm not sure if this is a new feature or is actually a bug that should be fixed. I would expect that a single command-w should close the window completely.
