A new horizontal widget (1x1...5,1) with nearest birthdays (for 5x1 widget - 5 events) with contact photo, age, days before event and full contact name
Hi, you can do it with day list widget. Just set it to show only birthdays.

I think it is already possible by choosing which calendar(s) to show in the widget, instead of showing the same as in the app. Choose "Agenda" mode widget and, in its settings, tab "General", scroll down to "Activated calendars" (or something like that - mine is in other language).
