Yes , we have already included that as a To Do before addons goes live.
I have also created a help desk ticket requesting for a space in Jira for Add Ons. This will further enable the community contribute to the development of this project. Once that is done we will edit the contributing.md on the github repository and also point to it from the addons webapp.
You may use this for feature requests. I have also edited the OP to include your suggestions and feature suggestions link.
Thanks for the pointers though !
