Where can I write a proposal for habraadmins?

Question

Habr

1. I would like the ability to delete my comment.
To remove the complexity, you can allow to delete only those comments for which no one voted for and for which no one answered.
You can even limit the possibility of deleting the time given to edit it (3 minutes from the post)
2. Once you start editing a comment, you can't undo it. You need to either save or refresh the entire page. Can you add another cancel button?
