Okay I am back and I have something in my mind.
So now the SharePoint 2013 is available and I am developing software upon that platform. Now very first things what I found from the change list was intresting “new” peopleeditor. When you create standard SharePoint list & add column that is type of People, then you’ll get the new looking people editor which allows email addresses and more importantly shows search results on below the editor.
The old peopleeditor got a few new properties such as “AcceptAnyEmailAddresses”, but more importantly there is new control named “ClientPeoplePicker”. This picker is actually being used in built in SharePoint forms. Old picker works the way it should be but this is intresting new control and I am still exploring the differences.
