Such a pref has been added some time.

I'm not getting rid of the delete icon, I use it all the time. A pref 
for all 3 sounds reasonable, though.

It'd be nice if this setting was split into either three options, or 
at least two options, where the Trash-icon was separated from the 
other two. Having the alarm and recurrence icons is nice, the 
Trash-icon muddles the view and isn't really needed there IMHO (I'd 
want to look at the event before removing it).



// show delete/alarm icons in the calendar view?

$_prefs['show_icons'] = array(

     'value' => 1,

     'locked' => false,

     'shared' => false,

     'type' => 'checkbox',

     'desc' => _("Show delete, alarm, and recurrence icons in calendar views?")

);
