Contacts section in major need of an overhaul

The Contacts list really needs to be overhauled. It would be good if you could do the following:

* Have the last email from said contact show up on the same section as their contact details
* Delete more than 20 people at a time
* Once you delete 20 people (or whatever the limit is) you return to your original spot, not the beginning of the list
* Add people I REPLY to but not necessarily those I INITIATE contact with
* Be able to edit contacts on a separate page, away from Gmail
* Have alphabetical tabs

This would be extremely helpful and make the Contacts section much much better.

Thanks!
