At the beginning, I got a problem with the add-on. But Alexander took the time to fix it. It is really nice to know that he is there to help you in case something go wrong. I totally recommend the add-on.

I love this app with core of my heart. I really appreciate the developer. It gives me the nostalgic feeling of working on a balck and white monitor. The developer has kept this app free this is also a great thing of appreciaton and applaud.

Dear Developer this is for you: CLAP! CLAP! CLAP! CLAP!
