This doesn’t seem to work on Ext.List, but you can add a List with “scroll:false” as a child of an Ext.Panel with “scroll:true” and add this listener to the Ext.Panel.  Now the next time the user goes back to that panel, they are at the top of the list, form, content, etc.

listeners          : {
  hide : function() {
    this.scroller.scrollTo({ x: 0, y: 0 })
  }
}

All you need to do is add this wonderful little listener and a timeout. If anyone knows how do do this globally as an override to the List type, I’m all ears.

listeners: {
  itemtap: function(record, index, item, e) {
    setTimeout(function(){record.deselect(index);},500);
  }
}

There are really only two approaches.  One is to send a notice to your server to send a particular user an email.  For lightweight requirements, you can just do this:

var msg = {
subject : "My genius email",
body : "Something about rabid squirrels in your coffee... nothing wakes you up, like rabies in your cup"
};
window.location = "mailto:" + MyApp.User.Email + "?" + Ext.urlEncode(msg);
