Stig How can I get this view to appear ?
As documentation says, it is in Main menu, File > Suggest new person…
Stig And how can I easily select a shortcut key on keyboard to auto-ignore-delete-face.
you can already navigate with keys on this dialog. Not a shourtcut exactly but still possible without touching a mouse.
Stig Alot of faces that I ignore comes up again, similar faces of the same person.
Are the ignored persons “stored” and forgotten ?
That depens on your choice - do you chose to delete them or not. If delted, they will never appear again. Hower, that does not mean all possible faces of that person will disappear, only few that were identified on this run. So that person can naturally show up again, but that will be different set of faces.
