Dragging Feature for DM's (Suggestion)

In the DM's tab when you click the home button, all of your DM's and Groups will appear (Groups that you haven't left or DM's you haven't closed). I think a great way to improve this listing would be to be able to drag groups or DM's into a certain area. This picture (the left one) is just an example but in order for me to switch the order that these friends DM's appear in, I would have to close one of the DM's and then open the other which would then put the DM to the original location on the list, and if I'm in groups that separate the DM's (Or other DM's that are opened) I wouldn't want to leave the group. With this dragging feature which would allow you to organize DM's and Groups (Just like how you can drag servers into a different order), it would help organize the way we want our DM's and Groups to be. Instead of our groups and DM's looking like this (middle most picture), they could look something like this (right picture). The right picture is just supposed to represent my friends in a row, I know it's only 3 but I used Inspect Element to change the Avatar and the name (Sorry I couldn't get any of my friends or groups in a row, which is why I think the dragging feature would be very helpful).
