Yo welcome on epvpers
I don't know if you saw it already, but I made an add-on for iBot. You can see the basic information(Look @ screenshots :P). But maybe if I have some spare time (probably if I'm done with school, in about 3 weeks) I can implement something like that, it seems nice anyway

.
On the other hand, why do you want to know how much damage you received? I understand that you want to know how much gold you gain/lose each loop or each hour, but I think it's pointless to know how much dmg you received?
Note, if you want to create a program yourself and you want that it works with ibot, you can only use the information ibot is giving you.
