What do you want to see on the next version of PD?
Altcoins?
probably this one because you mentioned few days ago that bitcoin transaction fees is finally getting out of the reach. Sooner or later it will be much higher, taking some precautions wont hurt
PVP/Multiplayer?
It is not really a popular game among gambler though a simple rock paper scissors game would be nice. I just cant remember if there is any site that has rock , paper , scissors game as PVP
Improved livestats/graphs?
Would be great, this kind of thing is pretty popular in the other site
