I have a few suggestions.
  1. Move Rows Per Page to the top instead of bottom.
  2. Allow Subcribe/Unsubscribe to be done with 1 click on Contacts page without going to "Edit" under Actions.
  3. When a user goes to edit, makes a change and hits save, have FMG go back to the contacts page with the same setting of Rows Per Page, and back to the same page the user was on before clicking edit to begin with. This way the user doesn't have to go back to choose "rows per page" then go back to the proper page (i.e. Set to 100 and click to go back to the page that shows contacts 101 +. It's too many clicks.
