Create "Delete All" functionality

Enhancement request (low priority): Create "Delete All" functionality

Situation: I have about 1,800 notifications accumulated for over a year. The problems are neither reportable nor serious. I would like to delete them all, but manually clicking on each one seems an overwhelming chore.

Desired outcome: It would be great if I could delete them all at once, whether by "Select all" > "Delete" or simply "Delete All".

(The root cause of all the notifications is a video driver that routinely causes a kernel oops. Because NVIDIA.)

Thank you for the fine work you do.
