This picture has been released by the Gulden development team and shows a test wallet on the Gulden 2.0 test environment. So the numbers shown are imaginary only. 

As we are getting closer to the release it’s nice to see how witnessing will look like. As you can see we have two lines. The grey one is your predicted earnings, as the blue one is your current earnings. Earnings will depend on the total weight of Gulden put into witness by all users.

In the lower left corner you can switch between view modes/change units.

We also can distinct that you will be able to use multiple wallets on one account. Nice!
