Delete calender reminders which are in the past automatically!
To avoid crowded list boxes with past calender reminders let them be deleted automatically. I had more than 450 past reminders which could not get geleted in the new web interface.

It would be nice to have this as an option rather than an enforced 'feature'. E.g. a tickbox in the settings of the webmail for the user that says 'ignore reminders for past events'.
