Looks good so far, the processing was indeed much much faster. And the progress bars are awesome!

What still remains is the problem with "," and "." interpretation of balances within the balance overview which shows super high amounts.

And I tested something else what normally shouldn't happen, but this may be handled nevertheless:

I'm using different wallets and I used the MSC wallet with Masterchest, then deleted all Masterchest folders, downloaded the new GitHub version, but changed the wallet.dat inbetween. After starting the new version for some reasons the addresses from the MSC wallet were still shown under addresses, but if I try to send coins, it only shows those from the new wallet. I'm actually a bit surprised, because I deleted also the wallet.sdf etc.
