I recently came across a post by Jim Naroski on The Office 365 Guy TechNet blog site. He listed the links to the UserVoice portal for the various products or topics which Microsoft utilizes to gather feedback and feature requests. One important link is missing from the TechNet blog, which is for the System Center Configuration Manager (ConfigMgr) feedback site, and I have added that to the list below. Start using this valuable resource to help improve products and make your voice heard.
Uservoice provides an opportunity for customers or end users of products to provide feedback, request features and interact with others as well as with the product teams. If you discover a request or feedback that you agree with and would like to support, you can add a vote to that post. Each UserVoice member receives a limited number of votes to use and these votes are returned once the the particular feedback has been acknowledged and completed. See above screen capture.
Another useful feature of UserVoice is the ability to see the status of the posts such as Noted, Planned, Under Review, Started, and Completed. See examples below:
