Nice!
Hey I want your opinion on some charting since you really wanted it included into the wallet.
I was thinking about where I could place some charts and what charts to do. The difficulty chart I moved over to the Statistics page here, looks pretty decent and updates the last 2 days of POS difficulty.

But the thing is that the code from philosophercoin basically says "if POS is not active, do not show the POS difficulty but instead show the network Stake Weight"
The easiest charts that could be included would be "POS difficulty", "Total Network Stake Weight" and "Your Total Stake Weight"
Other charts would be more complicated to do and retail space is a bit limited as well, could possibly create a new tab for a few charts though.
