Suggestion

Hello,
 
First, let me apologize for my English, which isn’t my first language.
That being said, I wanted to contact someone working in W3C  to suggest an idea. After a few years of web dev and many discussion with other developers, we came to the conclusion that today’s web browser lacked one particular functionality, that should be added and unified/standardized.
I’m not sure who I should address to and how I should do it, but I’m wishing to try.
Please indicated me, if possible, the right person for that.
 
Thank you in advance.
