Mac notifications disappear before I have a chance to view them. I'd like them to linger longer on the screen, so adjust the bannerTime value.
Of note, need to log out and back in for this to take affect.
$ defaults write com.apple.notificationcenterui bannerTime SECONDS
$ grep -r notifications_subscription_list_form contrib
contrib/notifications/notifications.module: $form['#submit'] = 'notifications_subscription_list_form_validate';
contrib/notifications/notifications.module: $form['#validate'] = 'notifications_subscription_list_form_submit';
Submit as validate and validate as submit. This is going to be interesting as I dig into the code.
