    • Hi,

      Thanks for the kind words 🙂 It’s nice to have the time again.
      Re: Tempest – I’ve checked on development – or lack of it. Seriously, WTF is wrong with that company? It’s a shocking way to treat your customers. I can’t believe people are still expecting improvements. It’s all bullshit to sell a few more units, pure and simple.
