It would be great if you could submit a feature requests via our contact page (github.com/contact). GitHub Staff working in the Forum will see and respond to those requests there.
That said, I do want to share that we are working on a new tool and process for submitting these sorts of things for the Community Forum (and for github.com). This is still in the investigative stage, and I don’t have a timeline to share, but we are planning on improving this process.
We also recognize the desire for feature requests to be visible to other users, commented on, and even voted on. These are all things that we are taking into consideration when looking at implementing a new process.
Thank you so much for the feedback! I encourage you to send your feature request via the contact form linked above.
Please let me know if you have any other questions.
