Request for improved Messages page (mm_main)

Hi,

In the Messages page within the dashboard (mm_main) it would be great if the messages could be sortable in date order. By default, it would make more sense to have the latest messages appear on top of the older ones.

Also, instead of the users column, how about replacing with From and To so that we can see at a glance who is messaging who.
The total message column seems kind of redundant, how about replacing with the message sent date.

Just some suggestions to make this plugin even better!
Thanks
