I'm on Windows 11 23H2, and to be clear, the behavior that I intend when I click the little cross on a popup notification is to completely dismiss it, not have it go to my notification area.
I assume the answer is no, since I have not seen any evidence to the contrary, but I just wanted to ask anyway (maybe Windows 11 has a way to do this that I don't know 🤷). This is something I've always hated about windows and I regularly look it up, but either not enough people care, or I'm the only one that wants this(?
