DataGrid is chronologically the last thing on that roadmap. It won't be available for several months. I haven't looked at the DMXZone version, but ours will likely be built to create a spreadsheet-style database manipulation experience. It will likely include reordering, search, insert, update all from a single page. Since we aren't completely done with our planning I really can't give a final feature list or definitive answer as to what it will incliude or when it will be available for sure. The only thing we have determined is that it is on our roadmap and we will investigate all of the features it will need to be a success.
A lot of people have mentioned they would like an unstyled form option. We will definitely consider adding that feature in a future release. Thank you for the suggestion.
We will be adding a forum to help people who want to give more feedback. This forum is specifically for Support, so we really want to keep that focus here and create another forum for non-support related feadback. The Announcements Discussion was a clear example of a forum athat encouraged non-support related posts. That is why we removed it. We will be creating a more appropriate area for this type of feedback in the upcoming months.
