Earlier version.
The Options window now fits on screen: two columns, resizable and scrollable.
New choice, off to begin with: the decks you built in Arena can appear in your account on the website, with the name you gave them. The name stays in your account and does not go into public statistics.
On the website: the Event filter shows all events, ticket text is readable and the anti-spam check works.
If you already have MOX you get the update automatically.
