things should be available in treo650

there are some small features, that i believe should exist in treo 650.

1. a default contact button.
   a lack of default contact button, requiring you to goto main application then tap on contacts. but to overcome that, we can create a shortcut;
   1. go to preference on main application,
      
   2. then select button, then you can assign option + [some button] for contacts
   
   
2. direct delete for SIM phonebook from contact.
   you need go to to SIM book to do the delete action
3. middle name field in contact.
   if you're using Microsoft Outlook, then you filled in middle name field in there, after syncronizing, you fill find the middle name is missing from treo 650 contacts.
4. filter syncronize
   on palm OS 4. it need HotSync to syncronize, the latest HotSync is capable to only syncronize filtered data, no need all.
