Hey Andreas, great job!

I leave you a feedback.

I have been able to test it on Linux. It works great!

On Windows no (it doesn't recognize any USB device). I tried Trezor, Jade, Ledger and none of them worked.

The setup wizard is very clear. Congratulations!

Here are some comments:

1. I have my OS in dark mode, and I found several fields that are not very legible. You could check the colors and contrasts (I leave you some screenshots).

2. I have not been able to spend the coins that are pending confirmation on the network.

3. I did not find the option to delete the coins categories.

I will keep testing and let you know more.
