Reset the poke after repoke

Hello thank you for your plugin,

Here is my question:
Now this is a cycle like: poke->poke back->poke back->…
I would like to reset this cycle after the first poke back : poke->poke back->reset
After poking back the cycle stop and the button from the start “poke” coming back instead of an infinite poke back between the two users.
Could you help me to modify your code to have this result ?

Also I suggest few improvements for next update :
-possibility to cancel a poke (from the user who poked)
-possibility to reject a poke (from the user who get poked)
-possibility for email notification after a poke
-Add the Pokes to the buddypress panel menu (top and side menu with notifications, messages …)

Thanks you by advance and keep up the great work.

Alban
