Hi folks,
We're embedded systems engineers who just made a serial monitor, Monitor. It's easy to configure, allows you to quickly filter messages, append special chars to messages, and toggle between hex and ASCII-views.
If you'd like to be involved in early development and give us your feedback, please sign up on the website to receive a copy. We're really looking forward to the Arduino community's thoughts on the product so we can make it as easy to use and powerful as possible.
I look forward to your responses and thanks for the help! 
Keep tinkering,
Nikita
