I have been back into DM after a short break away from it's use. I have found that text now appears along the center line referencing that the width, depth, or shape of the duct has been locked. This is a great new feature. However, I feel that one of the most important features that could be shown as locked is that of the CFM. In a quick duct sizing and CFM check, by locking the CFM of the end duct in the various branch strings, one can size and determine very quickly how a system is going to be. It would be beneficial to be able to see if the CFM has been locked as well as the W, D, and S.

Many times on complicated drawings I have a circuit that feeds multiple floors of devices or large areas. When I do Find Circuit, DM will zoom way out, highlight all the devices, and put lines to them. As soon as I try to find those far away circuits the lines disappear and then I start the needle in the hay stack look. If I has sort by circuit id, then callout I could see all the devices and then select find on each device of that circuit till I select the one in question since it creates a line that doesn't go away.
