Since 2010 I provide a way to parse an ATR online using a web page. I also provide a Python script to do the same using a command line tool.
I am not a user interface design expert. But I like to have important elements in color. Syntax colorization is a great invention. So I decided to add color to the ATR parsing results.

Conclusion
I like colorization.
This is dummy text. It is not meant to be read. Accordingly, it is difficult to figure out when to end it. But then, this is dummy text. It is not meant to be read. Period.
